At 240 VAC this MCCB clears 220 kA; at 415 VAC it's still 154 kA, and at 440 VAC it holds 121 kA. Those are the numbers a site electrical engineer checks first for SCCR compliance on a transformer secondary or a generator main. The curve drops to 17 kA at 500 V and 690 V — still enough for most 600 V class industrial services, but if you're coordinating upstream of a 690 V drive, verify the let-through against your transformer impedance. Rated 80 A at 40 °C ambient, it holds that figure through 50 °C, then drops to 78 A at 55 °C and 74 A at 70 °C. That's a shallow derating curve — useful in a crowded panel where ambient climbs. ## Integrated trip and auxiliary switchgear This breaker ships with a trip indicator (mechanical flag, no voltage trigger) and an undervoltage release (UVR) built in — the UVR drops the breaker if control voltage falls, standard for emergency-stop or undervoltage protection schemes. That saves an add-on module in most panels. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA footprint. The supplied basic switch is order code 3VA11806EF320AA0, meaning the internal mechanism is a known subassembly; if you're replacing an existing 3VA breaker in a panel, the mounting hole pattern and bus-bar spacing are consistent across the 3VA family.","metaTitle":"Siemens 3VA1180-6EF32-0BH0 SENTRON MCCB, 80A, 3-Pole, 220kA","metaDescription":"Siemens SENTRON 3VA1180-6EF32-0BH0 molded case circuit breaker, 80A rated at 40°C, 3-pole, 220 kA breaking capacity at 240 VAC.
