The 80 A rating holds flat from 40 °C through 50 °C; above that it derates to 78 A at 55 °C and 74 A at 70 °C, so if your panel ambient runs hot, size the feeder for the derated figure, not the nameplate. The interrupting curve here is steep: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That 17 kA floor at higher voltages is the number that governs most industrial panels on 480 V or 600 V class systems — it's still a high-interrupting frame, but the margin over a typical 25 kA or 65 kA SCCR requirement is what buys you selectivity headroom with downstream breakers. The TM240 thermal-magnetic release gives a fixed time-current curve; no electronic adjustment, so coordination studies need to account for the fixed magnetic pickup. ## Panel integration Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that drops into SENTRON distribution panels and most DIN-rail-mount enclosures with the appropriate adapter. The shunt trip release (STL) adds a pair of control wires for remote tripping; verify coil voltage compatibility with your trip circuit before wiring.","metaTitle":"Siemens 3VA1180-5EF36-0JA0 SENTRON MCCB, 80 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1180-5EF36-0JA0 molded case circuit breaker, 3-pole, 80 A rated at 40 °C, 187 kA interrupting at 240 V.
