Breaking capacity sits at 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That's enough headroom for most industrial service entrances or sub-feeders on a 480Y/277 V system — the 415 V figure covers the common 400 V class installations across Europe and Asia. It's the workhorse variant: set it, torque it, and move on. The 2 auxiliary switches (HP type) give you status feedback for the PLC or alarm annunciator without needing a separate aux block. ## Temperature derating and panel fit Above that, it steps down: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB spacing that drops into a SENTRON panelboard or a DIN-rail adapter plate. It's not a contactor; don't cycle it daily as a motor starter. The latching mechanism is robust for its class, but the TM240 release is what governs the trip characteristic, not a separate electronic trip unit.","metaTitle":"Siemens 3VA1180-3EF36-0AB0 SENTRON MCCB, 80 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1180-3EF36-0AB0 molded case circuit breaker, 80 A rated at 40 °C, 3-pole, TM240 thermal-magnetic release.
