The breaker occupies a 76.2 mm wide by 130 mm tall by 70 mm deep footprint — three standard 25 mm DIN modules wide. The front face is IP40, so it is suited for enclosed distribution boards where the door is closed during normal operation. No undervoltage release, no shunt trip, no communication function, and no ground-fault monitoring are built in; this is a plain thermal-magnetic line-protection MCCB. If you need auxiliary contacts or remote tripping, you will add those as external accessories.","metaTitle":"Siemens 3VM1140-3EE32-0AA0 SENTRON MCCB, 3-Pole, 40 A, 76 kA","metaDescription":"Siemens SENTRON 3VM1140-3EE32-0AA0 molded case circuit breaker, 3-pole, 40 A rated, 76 kA breaking capacity at 240 VAC.
