Insulation voltage is 800 V, and the interrupting capacity reaches 440 kA at 240 V, 330 kA at 415 V, and 220 kA at 500 V, so it handles high-fault utility feeds without cascading upstream. The interrupting capacity at 690 V is 52.5 kA. At 440 V, the rating is 330 kA. The ETU550 release supports LSIG protection; the ground-fault monitoring version is not included on this variant.","metaTitle":"Siemens 3VA2140-8JP36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU55","metaDescription":"Siemens 3VA2140-8JP36-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 3-pole, ETU550 release, 440 kA at 240 V.
