Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V, giving it headroom for high-fault installations. ## Panel Integration Mounts via screw terminals to a backplate or DIN rail adapter; the 4-pole unit occupies the same width as four single-pole spaces in a typical panel layout.","metaTitle":"Siemens 3VA2040-5JP42-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2040-5JP42-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU550 electronic trip unit, 187 kA at 240 V.
