Breaking capacity climbs with voltage: 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V — that spread covers most industrial LV distribution boards without an upstream current-limiting fuse. ## Thermal performance and panel fit At 80 A the maximum power loss is 19 W — modest enough that standard DIN-rail or base-mount spacing in a ventilated enclosure handles the heat without forced cooling. The 4-pole width (101.6 mm) matches the standard 4-module MCCB footprint for panel cutouts and busbar layouts.","metaTitle":"Siemens SENTRON 3VM1180-3GE42-0AA0 4-Pole MCCB, 80 A, 76 kA","metaDescription":"Siemens SENTRON 3VM1180-3GE42-0AA0 molded case circuit breaker, 4-pole, 80 A rated current, 76 kA breaking capacity at 240 V AC.
