BUCHANAN Terminal Blocks ## **100 Series High Density Miniature Blocks** ## **Product Facts** - n **No Wire Crimping Required — tubular clamp contacts hold wire ranging from #30 to #12 AWG better than crimp-on terminals.** - n **Saves Installation Time and Costs — tubular clamp contacts are supplied with captive screws backed out.** - n **Nylon housing standard; polypropylene for fire retardant characteristics.** - n **Positive Stop — helps prevent wire from being inserted too far, and helps prevent screw from being tightened on insulation. Easy access contact provides for safe, reliable, and costeffective connection.** - n **Quick Installation and Change — additional sections may be added or removed without removing channel mounting screw.** - n **Choice of Five Mounting Channels:** - n **Miniature aluminum** n **Zinc-plated steel** n **Pre-punched aluminum** n **Break-away steel** - n **Single and Double Tier blocks fit all standard BUCHANAN mounting channels. Single Tier blocks fit both miniature and standard channels.** These miniature terminal blocks fit on a much smaller channel to save valuable panel space or can be surface mounted directly to the panel. Miniature blocks accept wire as large as #12 AWG and are available in four styles: Miniature (nylon), Miniature (polypropylene), Single Tier and Double Tier. - n **Choice of Marking Surfaces — matte-finish area for marking directly on block; slide-in vinyl strip (blank or preprinted) also available.** **LR25557 E63810** 245 USA: 1-800-522-6752 Canada: 1-905-470-4425 Mexico: 01-800-733-8926 C.

BUCHANAN Terminal Blocks ## **ERT Series, Medium Duty Radiation Resistant** ## **Physical Properties** ## **Effect of Radiation on Physical Properties** The effects of radiation (neutron and gamma particles) on RYTON R-4 material have been studied. Since RYTON, as an engineering plastic, may fill applications in nuclear installations these effects are important. The test results show no effects on physical properties by these relatively high exposures to gamma and neutron radiation. There is no indication from these data of crosslinking or degradation of the RYTON R-4 material. **Note:** Determination of the suitability of the ERT Series Blocks for particular applications rests solely with customers. |**Description**<br>StrapScrew<br>Tubular Clamp<br>Tubular Screw|**Catalog**<br>**Number**<br>0721ERT<br>0725ERT<br>0724ERT|**Part**<br>**Number**<br>1437394-9<br>1-1437394-6<br>1-1437394-1| |---|---|---| |End Section|0730ERT|2-1437394-0| |**Housing: RYTON(Polyphenylene Sulfide)**|**Housing: RYTON(Polyphenylene Sulfide)**|**ASTM Test**| |---|---|---| |Density|100 lbs./ft.3|D1505-68| |Tensile Strength|19,500psi|D638-72| |Elongation|1.3%|D638-72| |Flexural Modulus|1,700,000psi|D790-91| |Flexural Strength|29,000psi|D790-91| |Compressive Strength|21,000psi|D695-69| |Izod Impact Strength||| |Unnotched, 1/8” Specimen|8.0 ft. lbs./in.|| |Notched, 1/8” Specimen|1.4 ft. lbs./in.|| |Rockwell Hardness|R-123|D785-65| |Water Absorption|0.05%|D570-63| |Heat Distortion Temp. @ 264psi|500˚F|D648-72| |Specific Heat, 24 hrs. @ 25˚C|0.25 btu/lb./˚F|| |Thermal Conductivity|2.0 btu-in./h-ft.2 F|| |Coefficient/Linear Thermal Exp.|2.5 x 10-5 in./in./˚ F|| |Flammability, UL 94|V-0|| |Dielectric Strength|350 volts/mil|D149-64| |Dielectric Constant, 25˚C 1 kHz|3.9|D150-70| |1MHz|3.8|| |Dissipation Factor, 25˚C 1kHz|0.0010|D150-70| |1MHz|0.0013|| |**Conditions**|**In Reactor Core**|**In Water Pool**| |Temperature|35˚C|30˚C| |Radiation|Mainlyneutrons|Mainly gamma| |Intensity|1010 ergsg-1(C)|109 ergsg-1(C)| |Used Particle Detectors|Calorimeter and<br>activation detectors|Ionization chamber| |**Radiation Dose**|**Flexural Strength**<br>**psi**|**Modulus of**<br>**Elasticity, psi**| |0|28,700|1,900,000| |**A.

BUCHANAN Terminal Blocks ## **Pre-Printed Marking Strips** Circuit identification is greatly simplified with the use of pre-printed strips for BUCHANAN terminal blocks. These hot-stamped strips are available for all snap-assembled sections (except Fuse, Switch, and Circuit Breaker models which are marked individually). The strips can be ordered separately or pre-installed on factory assembled sectional block units. Unlike painted or screened letters, hot-stamped letters are designed to not rub or flake off during industrial use so that they will retain their legibility. Marking strips are stamped with consecutive numbers that can be ordered to read from left-to-right or right-toleft, and in vertical or horizontal positions. Number sequences can begin with any number. This allows circuits to be identified in a manner most consistent with the terminal block application. ## **M 50 005 13 G** ## @ **A** @ **B** @ **C** @ **D** @ **E** - e@ **A M** = Hot-Stamped Marking Strip @ **C Number of Circuits to be Consecutively Numbered** - @ **B Terminal Block Series and** (Use three digits: Ex.: 005 = 5, **Designator** 055 = 55, etc.) **10** = Miniature or Single Tier **12** = Double Tier @ **D Marking Style Options 67** = 900 Series Medium Duty **11** = 1 2 3 4 5... **24** = Nylon Heavy Duty **12** = ...5 4 3 2 1 **21** = Phenolic Heavy Duty **13** = ... **80** = Intermediate Heavy Duty **14** = ... **40** = Ultra Heavy Duty **T2** = TSB230 @ **E “First Number In Series” T5** = TSB500 **Designator* A** = 1 **F** = 6 - **T6** = TSB1000 **B** = 2 **G** = 7 - **T7** = TSB2000 **C** = 3 **H** = 8 **D** = 4 **J** = 9 **E** = 5 **K** = 0 **Marking Strip Installed On A Factory-Assembled Terminal Block** ## **615 005 11 A** @ **A** e@ **B** @ **C** @ **D** ~~@~~ **A Basic Sectional Block Catalog #** @ **D “First Number In Series” Designator* A** = 1 **F** = 6 @ **B Number of Circuits to be Factory Assembled and Consecutively B** = 2 **G** = 7 **Numbered C** = 3 **H** = 8 (Use three digits: Ex: 005 = 5, **D** = 4 **J** = 9 055 = 55, etc.) **E** = 5 **K** = 0 ## @ **C Marking Style Options** - **11** = 1 2 3 4 5... **12** = ...5 4 3 2 1 **13** = ... **14** = ... * Letters in this position designate the first number to be used in the consecutive sequence. Ex.: “A” would start the sequence with the number 1. “EK” would start the sequence with the number 50. “BKK” would start the series with 200.

BUCHANAN Terminal Blocks ## **UL 1059 Basic Voltage Rating** Voltage ratings of terminal blocks are based on the minimum spacing between electrical conductive parts of opposite polarity or between an electrically conductive part and a metal mounting surface measured under two conditions: Through Air, defined as the distance an arc must take through the air to go from one live conductor to another or from a live conductor to ground; and Over Surface, defined as the distance an arc must take over a surface of the insulating material going from one terminal to ground, assuming the arc will travel along the surface rather than through the air. The following chart shows UL 1059 spacing requirements in inches. ## **Voltage Rating** |**Voltage Rating**|||| |---|---|---|---| |**Description**|**Voltage**|**Spacing Re**<br>**Thru Air**|**Requirements**<br>**Over Surface**| |Class A|||| |Service equipment including deadfront|51 - 150|1/2 [12.7]|3/4 [19.05]| |switchboards, panel boards, service|151 - 300|3/4 [19.05]|1 1/4 [31.75]| |entrance devices, etc.|251 - 600|1[25.4]|2[50.8]| ||||| |Class B|||| |Commercial appliances including|51 - 150|1/16 [1.59]|1/16 [1.59]| |business equipment, electronic data|151 - 300|3/32 [2.38]|3/32 [2.38]| |processingequipment and the like|251 - 600|3/8[9.53]|1/2[12.7]| ||||| |Class C|||| |General industrial and machine tools;|51 - 150|1/8 [3.18]|1/4 [6.35]| |controls which can be further defined|151 - 300|1/4 [6.35]|3/8 [9.53]| |as equipment fallingunder UL508|301 - 600|3/8[9.53]|1/2[12.7]| ||||| |Devices having limited ratingsa|51 - 300|1/16 [1.59]|1/8 [3.18]| ||301 - 600|3/16 [4.76]|3/8 [9.53]| aLoad on any single circuit can not exceed 15 A at 51-150 V, 10 A at 151-300 V, 5 A at 301-600 V or the maximum current rating, whichever is less. ## **Standard Test Criteria** |**Standard Test Criteria**|| |---|---| |**Test**|**Per:**| |Heat Cycling (term)|UL486E Section 10| |Static Heating (term)|UL486E Section 11| |Secureness|UL486E Section 12| |Pullout|UL486E Section 14| |HeatingTest(block)|UL1059 Section 10| |Dielectric Withstand|UL1059 Section 11| |Strength of Base|UL1059 Section 13| |Tab Pull|UL1059 Section 14| |VPTA|UL1059 Section 15| |Salt Spray|MIL-202 Method 101| |Solderability|MIL-202 Method 208| |Solvents|MIL-202 Method 215| 296 USA: 1-800-522-6752 South America: 55-11-2103-6000 Canada: 1-905-470-4425 Hong Kong: 852-2735-1628 Mexico: 01-800-733-8926 Japan: 81-44-844-8013 C.
