Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — covering most industrial distribution panels where high-fault service entrances or motor-control-center feeders need a 3-pole 80 A MCCB. ## Fit and panel integration — 70 mm deep, IP40 front, undervoltage release included At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard 3-pole MCCB panel cutouts and busbar arrangements; the IP40 front protection means it is suitable for enclosed distribution boards where splash or tool entry is not expected on the operator face. No auxiliary contact version is fitted as standard; if remote status indication is needed, the separate auxiliary trip block (order code 3VA9608-0BB24) can be added.","metaTitle":"Siemens 3VA1180-3EF36-0CA0 SENTRON MCCB, 80 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1180-3EF36-0CA0 molded case circuit breaker. 80 A rated, 3-pole, TM240 release, 75.6 kA at 240 V.
