The 400 A rating holds across ambient temperatures from 40 °C to 50 °C; above that it derates linearly to 367 A at 70 °C. ## Dimensions and mounting — fits standard MCCB footprints At 184 mm wide, 248 mm tall, and 110 mm deep, this breaker occupies a standard 4-pole MCCB slot in a SENTRON panelboard or separate enclosure. The IP40 front protection suits indoor panel installations where tools or fingers might contact the front face. Maximum power loss of 92.1 W must be factored into the enclosure thermal budget — not a concern in a ventilated switchboard, but worth checking in a sealed stainless-steel box.","metaTitle":"Siemens 3VA1340-6GE42-0AA0 SENTRON MCCB, 400 A, 4-Pole, TM22","metaDescription":"Siemens SENTRON 3VA1340-6GE42-0AA0 molded case circuit breaker, 400 A, 4-pole, TM220 release, 154 kA at 415 V.
