nte8065 thru nte8242 thermal cutoff (thermal fuse) description: twenty one thermal cut ? offs (also known as thermal fuses) are now included in the nte product line. they are minia- ture, non ? resettable temperature sensitive devices designed to prevent appliances and electronic equipment from overheating. nte thermal cutoffs are ul and csa listed. literally thousands of different applications have been devised for thermal ? cutoffs, thus providing a large replacement market. such applications include: ? hair dryers ? refrigerators ? battery chargers ? irons ? hot plates ? glue guns ? electric motors ? window fans ? coffee makers ? microwave ovens ? popcorn poppers ? dishwashers ? toasters ? ups ? and hundreds of others the tco (thermal cut ? off) responds to temperature by interrupting an electrical circuit when the operating and/or envi- ronmental temperature exceeds the thermal rating of the device. this is accomplished when the internal organic pellet experiences a phase change, allowing the spring activated contacts to permanently open the circuit. nte type no. diag. no. functioning temperature holding temperature maximum temperature c f c f c f 8065 193 66 151 42 108 130 266 8070 193 72 162 50 122 115 239 8076 193 77 171 ? ? ? ? 8081 193 84 184 60 140 125 257 8085 193 87 189 ? ? ? ? 8090 193 93 200 ? ? ? ? 8096 193 98 209 76 169 140 284 8098 193 100 212 ? ? ? ? 8103 193 104 220 80 176 150 302 8108 193 109 229 88 190 140 284 8115 193 117 243 ? ? ? ? nte type no. diag. no. functioning temperature holding temperature maximum temperature c f c f c f 8118 193 121 250 94 201 170 338 8125 193 128 263 106 223 155 311 8139 193 141 286 117 243 171 340 8149 193 152 306 128 262 176 349 8167 193 170 338 146 295 300 572 8181 193 184 364 160 320 300 572 8182 193 192 378 162 324 290 554 8213 193 216 421 191 376 241 466 8226 193 228 443 ? ? ? ? 8242 193 240 464 200 392 290 554 electrical rating volts interrupting continuous 120/250 vac 15a 10a 240 vac 25a res 16.7 res 277 vac 20a res 15a res electrical rating volts interrupting continuous 120 ? 277 vac 125va pilot duty 180 vac 3a motor rating features: ? maximum current rating: 15 amps ? typical opening temperature tolerance: +0 c, ? 5 c ? 18 gauge solid copper wire ? full 1 1/3 ? leads to fit all replacement configurations ? all types meet the requirements of underwriters laboratories specifications, csa, and vde. ? each device comes packaged with 2 crimp splices for solderless connection. ul file no. e49429 ul file no. e117626 (guide # xcmq2) c ? ul file no. e117626 (guide # xcmq8) csa file no. lr43279 vde file no. 115369 note 1: temperature sensitive devices. do not store above +48 c (+120 f). note 2: color band does not denote temperature group. note 3 : the electrical resistance of the nte series thermal cut ? off is comparable to that found in an equal length of 18 gauge solid copper wire. with proper air flow, heat generation below 15 amps is minimal, above 15amps the upper limit on the currentcapacity will depend on the envi ronment for each specific application. note 4: a general rule of thumb for continuous operating temperature for thermal cut ? offs is 30 c less than the maximum opening t emperature. 1.380 (35.0) case end .457 (11.6) max .160 (4.1) dia max 1.383 (35.1) ** epoxy end note: tin plated lead note: silver plated lead diagram 193 3.220 (81.78) max ** some devices may have a lead length of .980 (25.0)
