The unit is ideal for branch circuit applications such as EDP, air conditioners, panel boards and lighting controls. The 209 is actually a family of circuit breakers available in one through six pole assemblies with a variety of configurations and terminal styles to meet your application needs. First in this family is the 209, a general purpose E-Frame circuit breaker which complies with UL Standard 489. Other members of the family include the 219, for manual controller applications, which complies to UL Standard 508, the 229, for supplementary protectors applications, which complies to UL Standard 1077, and the 299, a Special Construction version. Utilizing the hydraulic-magnetic principle, the 209 family adapts itself to local applications and environments. Temperature conditions, which affect fuses and other thermal devices, are not a concern. The magnetic /ampere turn principle minimizes nuisance tripping due to temperature variations. Inrush currents, due to ferroresonant transformers, lamps and capacitive filters, are now becoming more significant. Recognizing the need for this type of protection, Airpax offers the unique inertial delay which is standard for all 50/60Hz time delay units, but may be deleted where inrush is not a problem. No extra cost or special order is required. The 209 family of circuit breakers withstands high pulses without tripping or affecting normal delay curves. This performance, however, does not derate or sacrifice protection. **187** _209 Series - Introduction_ http://airpax.sensata.com ## **209/219/229 MAGNETIC CIRCUIT PROTECTORS** ## **Terminal Style** 209 E-Frame circuit breakers may be specified with either screw terminals, stud or solderless connectors.

The 249 is designed to allow selection of any one of two, three or four independent power systems. This is accomplished with fool-proof sliding-gate handle covers. The number of sliding covers is one less than the number of power systems. With this arrangement, it is impossible to switch “ON” more than one power system at a time. Since the 249 Power Selector Breaker System is listed as a Branch Circuit Breaker per UL 489 and power switching is accomplished by UL listed breakers, it is usually not necessary to include additional branch service protection. ## **Trip Time Delay** Three inverse time delays are available to permit close coordination with various loads. Delays 51 and 61 are short delays for electronic loads. Delays 52 and 62 are medium delays for mixed loads. Delays 53 and 63 are long delays for motor loads. ## **Current and Voltage Ratings** Single pole and multi-pole breaker ratings are available up to 100 amperes, 240Vac or 125Vdc. The special configuration for Marine use has a 120V/240Vac rating for current rating up to 100 amperes. ## **Master Drawing** Standard circuit breaker terminal and configurations are shown. For other types, consult factory. Standard options available include terminals for front or back connections, choice of trip time delay, current ratings to 100 amperes and single or multi-pole sections. _209 Series - 249 Power Selector Breaker System_ http://airpax.sensata.com **189** ## 249 Master Drawing **==> picture [563 x 390] intentionally omitted <==** **----- Start of picture text -----**<br> 2.610<br>Width [20.32].800 [66.29] 1.220<br>(SEE TABLE) .562 MAX.

Handles are ganged externally for simultaneous actuation. Individual poles may differ in ratings, delays and configurations, providing an almost limitless number of combinations. Multi-pole protectors (up to 6 poles) easily satisfy special modern day circuitry. Series, shunt, relay and auxiliary switch construction add to the versatility of design engineering. Airpax’s sales engineering force is ready to assist in proper unit selection, both for equipment protection and economical design. ## **Three Phase, Four Pole Includes Control Protector** Remote shutdown of equipment is sometimes necessary or desirable in today’s sophisticated equipment. The 219 four pole assembly fills this need for three phase operation. Three of the four poles are designed for the circuit’s proper operating current and over-current protection. The fourth pole may be designed for instantaneous tripping by logic circuitry, interlocks or from a manual remote site or control. The control power required would be quite low, with voltages from 5 to 125Vdc, or 5 to 240Vac available. The fourth pole construction is optional. It may be either series, shunt or relay, depending on the application required. When specifying, both the minimum trip voltage and Hz are required. Factory consultation is readily available.

This specification requires devices to be used in accordance with the requirements of U.S. Coast Guard and Fire Protection Standard for Pleasure and Commercial Motor Craft, ANSI/ MFPA No. 302. ## **Series Trip** The most popular configuration for magnetic protectors is the series trip, where the sensing coil and contacts are in series with the load being protected. The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it’s simultaneously used as an ON-OFF switch. The ratings available are 100 amperes or less at 65Vdc or 240Vac. Maximum IC, 1000 amperes. Consult factory for application details. The 299D series is available with interlocking to prevent on board and shore power being used simultaneously. Combination of ON-OFF switching the protection function offers a simplified solution for your electrical systems. ## **UL 489A Communications Equipment Protection** The 279 Series complies with the requirements of UL 489A, Circuit Breakers for use in Communication Equipment, meeting the need for protection at higher DC voltages. The available ratings are 100 amperes or less at 160Vdc. Maximum short circuit interrupting current is 5000 amperes. The 279 series available only in a series trip configuration. **==> picture [166 x 184] intentionally omitted <==** **----- Start of picture text -----**<br> SEE NOTE A<br>LINE<br>LOAD<br>3.550<br>[90.17]<br>.750<br>[19.05]<br>**----- End of picture text -----**<br> Please consult Sensata for specific application details. ## **Auxiliary Switch** This is furnished as an integral part of a series pole in single or multi-pole assemblies. Isolated electrically from the protector’s circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protector’s ON-OFF status.

The coil may be actuated by sensors monitoring pressure, flow, temperature, speed, etc. Other typical applications include crowbar, interlock and emergency/rapid shutdown circuitry. Trip may be accomplished by voltage or current, which must be removed after trip. ## **Dual Coil** Providing for both a voltage trip and a current trip function in a magnetic circuit protector is common practice. These two coil protectors provide remote or automatic opening of one or more circuits with a low level signal. The voltage coil will trip the protector instantaneously while the current coil provides normal inverse time delays. The voltage coil is not rated for continuous duty and therefore, the voltage must be removed when the breaker trips. **==> picture [240 x 193] intentionally omitted <==** **----- Start of picture text -----**<br> SEE NOTE A<br>LINE<br>LOAD<br>1.000 RELAY<br>[25.40]<br>RELAY<br>3.550<br>[90.17] LINE<br>COIL<br>COIL<br>Relay Trip LOAD<br>1.250<br>[31.75]<br>.750<br>[19.05]<br>Dual Coil<br>.190<br>[4.83]<br>**----- End of picture text -----**<br> Since both coils are housed within the same pole, the space savings are substantial. This option is not available with 64, 65 or 66 delays. ## **Shunt Trip** The shunt trip is designed for controlling two separate loads with one assembly. The control is established by providing overload protection for the critical load. When the current through this load becomes excessive and reaches the trip point, the protector will open and remove power from both loads simultaneously. The total current rating of both loads must not exceed the maximum contact rating. ## **Voltage Trip** Sometimes called “dump circuits” or “panic trip circuits,” these units make it possible to open main power contacts with lower power inputs from one or more sources. This configuration is becoming increasingly more important for sensitive circuitry and denser packaging in automation systems. Available in series, shunt or relay configurations. **==> picture [254 x 188] intentionally omitted <==** **----- Start of picture text -----**<br> SEE NOTE A<br>LINE<br>LOAD<br>SHUNT<br>[90.17]3.550 V.

Delay 61 is a short delay for general purpose applications. Delay 62 is long enough to start certain types of motors and most transformer and capacitor loads. Delay 63 is a long delay for special motor applications. Delays 64, 65 and 66 are the latest 50/60Hz delays with short, medium and long trip times respectively. The patented breaker design provides both increased tolerance to high inrush induced nuisance tripping and longer trip times at 600 percent. These delays are ideally suited for applications where thermal devices are presently used, such as motor protection or where short duration, high inrush currents are experienced. As shown in a typical motor start-up curve, the delay 66 will provide locked rotor and overload protection. Nuisance tripping is avoided, since acceptable short periods of overload will not trip the breaker. All trip curves and trip currents are specified with the breaker mounted in the normal vertical position at ambient temperature of +25°C. For test and measurement purposes, the breakers should not carry current prior to application of overload for calibration test.

The coding given permits a self-assigning part number for standard configurations. Factory part numbers are assigned to units with mixed ratings, combinations of styles or construction not listed in the Third Decision Table, etc. With these, it is suggested that order entry be by description and/ or drawings, and a part number will be established. Additionally, it is standard policy to establish a factoryassigned part number whenever a descriptive drawing exists to insure cross reference, traceability and manufacturing control. When specifying a breaker for AC motor start or high inrush applications, the peak amplitude and surge duration should be specified for factory assistance in rating selection. 209 is a UL listed circuit breakers under file no. E53739 per UL 489. **==> picture [235 x 201] intentionally omitted <==** * U 489 Listed units are rated to 100A maximum ** U 489A Listed units are rated to 160Vdc maximum 279 is a UL listed under file no. E192808 per UL 489A. 219 is a UL recognized “Manual Motor Controller” under file no. E41607 per UL 508. 229 is a UL recognized supplementary protector under file no. E66410 per UL 1077. For example, the following is the code for a single pole breaker with series trip, 50/60Hz, medium inertial delay, 120/240Vac maximum voltage ratings, solderless connector with mounting foot added to the line side of the breaker to facilitate back panel mounting and a current rating of 10.0 amperes. To determine the ordering number of your particular 209 unit, simply follow the steps shown. You may use this number to place an order or as a reference for further questions you may have. **==> picture [236 x 137] intentionally omitted <==** Notes: - A 6-32 inserts for front mounting are provided on all units. M3 ISO metric mounting inserts are available and are specified by adding -A at the end of the ordering code above. - B The auxiliary switch is located on the right-hand pole (viewed from terminal end) unless specified otherwise. Auxiliary switches are available on all front or back panel mounts (series construction only). If more than one auxiliary switch is specified use “2R” through “6R” as required. - C Line terminals are 10-32 screws for bus connection to 100 amperes. Load terminals are 10-32 screws to 50 amperes and solderless connectors from 50 to 100 amperes. - D An anti-flashover barrier is supplied between poles on all multi-pole versions with 10-32 stud and 1/4-20 stud terminals per UL requirement. - E The standard current values for 100% of rated current are those listed in the Seventh Decision Table. Non-listed values can be readily supplied, in general without delayed delivery.
