Delays 59 and 69 provide fast-acting, instantaneous trip and are often used to protect sensitive electronic equipment (not recommended where known inrush exists). Delays 51 and 61 have a short delay for general purpose applications. Delays 52 and 62 are long enough to start certain types of motors and most transformer and capacitor loads. ## **Trip Free** Will trip open on overload, even when forcibly held on. This prevents operator from damaging the circuit by holding handle in the ON position. ## **Trip Indication** The operating handle moves forcibly and positively to the OFF position on overload. ## **Ambient Operation** Operates normally in temperatures between –40° C and +85°C. ## **Insulation Resistance** Not less than 100 megaohms at 500Vdc. ## **Dielectric Strength** **==> picture [203 x 321] intentionally omitted <==** **----- Start of picture text -----**<br> 10000<br>1000 DELAY 63<br>100<br>10<br>1<br>.1<br>.01<br>.001<br>0 100 150 200 300 400 500 600 700 800 900 1000<br>125<br>PERCENT OF RATED CURRENT<br>10000<br>1000 DELAY 69<br>100<br>10<br>1<br>.1<br>.01<br>.001<br>0 100 150 200 300 400 500 600 700 800 900 1000<br>125<br>PERCENT OF RATED CURRENT<br>MAY TRIP<br>TIME IN SECONDS<br>MAY TRIP<br>TIME IN SECONDS<br>**----- End of picture text -----**<br> Shall withstand AC voltage 60 Hz, for 60 seconds between all electrically isolated terminals as described below. |Series, switch only<br>: 3,750 VAC| |---| |Auxiliary switches<br>: 600 VAC<br>Series w/ auxiliary switch : 3,750 between main circuit<br>breaker terminal and auxiliary<br>switch terminal| ## **Shock** Shall not trip when tested per MIL-STD-202, method 213, test condition 1 with 100% rated current applied to delayed units, except 90% current in plane 4, (i.e. handle down). Instantaneous units shall have 80% rated current applied in all planes. ## **Vibration** Shall not trip when vibrated per MIL-STD-202, method 204, test condition A with 100% rated current applied to delayed units and 80% rated current to instantaneous units. ## **Endurance** In many applications contact wear due to the electrical load determines unit life. At maximum electrical ratings, the IAR/IUR/IER/ CUR/CER can perform 10,000 operations at rated current and voltage at a maximum rate of 6 operations per minute. _IAR Series - Delay Curves & Specs_ **48** **==> picture [612 x 61] intentionally omitted <==** ## **OPERATING CHARACTERISTICS** ## **Inrush Pulse Tolerance** Many circuit protector applications involve a transformer turn-on, an incandescent lamp load, or a capacitor charge from a DC source. Each of these applications has one common factor: a steep transient of very high current amplitude and short duration. This takes the form of a spike or a single pulse and is the cause of most nuisance tripping associated with magnetic circuit breakers. The IAR/IUR/IER/CUR/CER series will withstand, without tripping, a single pulse of 8 milliseconds duration (half sine wave configuration) and peak amplitude of 10 times its rating. ## **MAXIMUM DCR AND IMPEDANCE (APPROXIMATE VALUES)** |**MAXIMUM DCR AND IMPEDANCE (APPROXIMATE VALUES)**|**MAXIMUM DCR AND IMPEDANCE (APPROXIMATE VALUES)**|**MAXIMUM DCR AND IMPEDANCE (APPROXIMATE VALUES)**| |---|---|---| |**Current Ratings**<br>**(Amps)**|**DC Resistance**<br>**(Ohms)**<br>**51, 52, 53, 59**|**50/60Hz Impedance**<br>**(Ohms)**<br>**61, 62, 63, 69**| |2.0|0.027|0.038| |3.0|0.074|0.098| |5.0|0.037|0.048| |7.5|0.025|0.029| |15.0|0.010|0.011| |32.0|0.003|0.003| |40.0|0.003|0.003| |50.0|0.0024|0.0025| |65.0|0.0021|—| |_Tolerance: 2 to 2.5 amps ±20%; 2.6 to 20 amps ± 25%; 21 to 50 amps ±50%_<br>_*Consult factory for special values and for coil impedance of delays_<br>_not shown_||| |**AUXILIARY SWITCH RATING**|**AUXILIARY SWITCH RATING**|**AUXILIARY SWITCH RATING**| |---|---|---| |10.0 amps|@|250 VAC, 60 Hz| |3.0 amps|@|50 VDC| |1.0 amps|@|80 VDC| |**APPROXIMATE WEIGHT PER POLE**|**APPROXIMATE WEIGHT PER POLE**| |---|---| |1pole|134grams| |2pole|263grams| |**PULSE TOLERANCE**|**PULSE TOLERANCE**| |---|---| |**Delay**|**Pulse Tolerance**| |61, 62, 63|10 Times Rated Current| ## **PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)** |**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**|**PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS AT +25°C (APPROXIMATE VALUES)**| |---|---|---|---|---|---|---|---|---| |**Delay**|**100%**|**125%**|**150%**|**200%**|**400%**|**600%**|**800%**|**1000%**| |51|No Trip|0.5 to 6.5|0.3 to 3|0.1 to 1.2|0.031 to 0.5|0.011 to 0.25|0.004 to 0.1|0.004 to 0.08| |52|No Trip|2 to 60|1.8 to 30|1 to 10|0.15 to 2|0.015 to 1|0.008 to 0.5|0.006 to 0.1| |59|No Trip|0.120 max|0.1 max|0.05 max|0.022 max|0.017 max|0.017 max|0.017 max| |61|No Trip|0.7 to 12|0.35 to 7|0.13 to 3|0.03 to 1|0.015 to 0.3|0.01 to 0.15|0.008 to 0.1| |62|No Trip|10 to 120|6 to 60|2 to 20|0.2 to 3|0.015 to 2|0.015 to 0.8|0.01 to 0.25| |63|No Trip|50 to 700|30 to 400|10 to 150|1.5 to 20|0.015 to 10|0.013 to 0.85|0.013 to 0.5| |69|No Trip|0.12 max|0.1 max|0.05 max|0.022 max|0.017 max|0.017 max|0.017 max| _IAR Series - Operating Characteristics_ http://airpax.sensata.com **49** **==> picture [138 x 135] intentionally omitted <==** **----- Start of picture text -----**<br> Barrier (-B)<br>1.460<br>[37.08]<br>1.715<br>[43.56]<br>Bullets<br>**----- End of picture text -----**<br> **==> picture [182 x 114] intentionally omitted <==** **----- Start of picture text -----**<br> Socket 1/4-20 UNC-2A<br>Order # 641-480-5032<br>(silver plated copper)<br>0.725 0.510<br>[18.42] [12.95]<br>0.251 ± 0.001<br>Ø<br>[6.38 ± 0.03]<br>0.375<br>[9.53]<br>**----- End of picture text -----**<br> **==> picture [246 x 235] intentionally omitted <==** **----- Start of picture text -----**<br> Socket 1/4-20 UNC-2A<br>Order # 641-480-5030<br>(silver plated copper)<br>0.725 0.510<br>[18.42] [12.95]<br>0.251 ± 0.001 0.375<br>Ø Ø<br>[6.38 ± 0.03] [9.52]<br>Socket 1/4-20 UNC-2A<br>Order # 641-480-5022<br>(silver plated copper)<br>0.725 0.510<br>[18.42] [12.95]<br>0.312 ± 0.001<br>0.438 Ø<br>[7.92 ± 0.03]<br>[11.13]<br>**----- End of picture text -----**<br> **==> picture [202 x 57] intentionally omitted <==** **----- Start of picture text -----**<br> Nut 1/4-20 UNC-2B<br>Order # 388-899-5010<br>(silver plated copper)<br>0.438 0.156<br>[11.13] [3.96]<br>**----- End of picture text -----**<br> ## **HARDWARE** ## **Handle Lock** A handle lock option is available to prevent accidental actuation of the handle.

It is available in single pole and multi-pole (handle per pole only) series constructions. Switch only configuration is not available in mid-trip build. An auxiliary switch can be furnished as an integral part of the mid-trip breaker. The switch provides an indication at a remote location when the circuit breaker has electrically tripped and handle is in the mid-trip position. **==> picture [50 x 114] intentionally omitted <==** **----- Start of picture text -----**<br> Mid-Trip<br>Position<br>ON<br>Position<br>OFF<br>Position<br>**----- End of picture text -----**<br> _IAR Series - Hardware_ **50** **==> picture [612 x 61] intentionally omitted <==** ## **HOW TO ORDER** The ordering code for these circuit breakers / protectors may be determined by following the steps in the decision tables shown here. The example shown is the code for a UL1077 & TÜV approved circuit protector with series trip, one handle per unit, single pole circuit protector with 10-32 terminal screws standard and a mechanical auxiliary switch. This unit is designed with a slow DC time delay and a rating of 20 amperes with optional metric threads and optional 80VDC capability. Handle color is black with white markings, and is has been met all the selection criteria to obtain the TÜV approval. 1 First Decision First Choice: Type Second Choice: Terminal IAR Magnetic circuit protector, one handle per unit 10-32 screw terminal, standard (no entry) IARH Magnetic circuit protector, one handle per pole K 10-32 stud terminal IER UL1077 & TÜV, series trip, one handle per unit B 0.250” bullet terminal IERH UL1077 & TÜV, series trip, one handle per pole IUR[UL1077, series trip, one handle per unit] The shaded areas denote TÜV approval IURH[UL1077, series trip, one handle per pole] options. This approval requires the IMR[UL1077 & TÜV, mid trip, one handle per unit] addition of a “T” at the end of the part number (8th decision). IMRH UL1077 & TÜV, mid trip, one handle per pole CER[UL489A & TÜV, series trip, one handle per unit] The “T” will automatically be added to any part number formed entirely from CERH[UL489A & TÜV, series trip, one handle per pole] these shaded decisions. If non-shaded CUR[UL489A, series trip, one handle per unit] areas are selected, the unit will not be TÜV approved, but other approvals (if CURH[UL489A, series trip, one handle per pole] applicable) will still apply. CMR[UL489A & TÜV, mid trip, one handle per unit] CMRH[UL489A & TÜV, mid trip, one handle per pole] To determine the ordering code for your particular unit, simply follow the steps shown, then fill in the letters and/or numbers in the boxes.
