Breaking capacity is 75.6 kA at 240 V, stepping down to 52.5 kA at 415 V and 32 kA at 440 V — enough for most industrial distribution panels where fault current is high at the main, but verify your point-of-installation SCCR against the lower 440 V figure if you're feeding a 400 V bus. The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm high — a standard SENTRON 3VA footprint that snaps onto DIN rail or mounts directly in a panel. The TM240 thermal-magnetic release is fixed, and the unit includes 2 auxiliary switches plus a trip alarm switch (HQ design).","metaTitle":"Siemens SENTRON 3VA1180-3EF32-0AH0 MCCB, 80 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1180-3EF32-0AH0 molded case circuit breaker, 3-pole, 80 A at 40 °C, breaking capacity 75.6 kA at 240 V.
