Breaking capacity is 440 kA at 415 V and 187 kA at 690 V — that's high enough to handle most transformer-fed fault currents upstream of a sub-distribution board without cascading failure. The 40 A rating holds flat from 40 °C through 70 °C ambient, so no derating headache in a warm enclosure or near other heat sources. Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — standard 3-pole MCCB footprint for a 160 A frame. ## Integration — panel fit and wiring notes The 86 mm depth leaves clearance for rear-access cable routing. The ETU330 trip unit is powered from the line-side current transformers, so no auxiliary supply needed. Ground-fault protection is built in (summation current formation on L-conductor), which saves adding a separate GFCI module downstream.","metaTitle":"Siemens 3VA2140-0HM36-0AA0 SENTRON MCCB, 40 A, 440 kA at 415","metaDescription":"Siemens SENTRON 3VA2140-0HM36-0AA0 molded case circuit breaker. 40 A continuous, ETU330 trip unit, 440 kA at 415 V.
