Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V, dropping to 7.5 kA at 690 V — numbers that govern whether this breaker clears a fault before the upstream device takes the hit. ## Thermal derating and coordination reality Above that, the curve drops 25 A per 5 °C step: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, 300 A at 70 °C. That matters when you're stacking breakers in a hot enclosure or near a transformer. The interrupting capacities across voltages — 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 500 V, 7.5 kA at 690 V — define the fault-clearing envelope for selectivity studies. If your upstream transformer can deliver 100 kA at 415 V, this breaker's 121 kA gives you headroom. Dimensions are 110 mm deep, 138 mm wide, 248 mm high — a 3-pole frame that fits standard switchgear cubicle cutouts. The auxiliary switch complement (2 aux + 1 trip alarm) is built into the supplied basic switch variant 3VA2340-5JP32-0AA0. Shunt trip release (STL) is included for remote tripping. Communication function is onboard, so this breaker can talk to a BMS or PLC without an add-on module.","metaTitle":"Siemens 3VA2340-5JP32-0KH0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-5JP32-0KH0 molded case circuit breaker, 400 A continuous, 3-pole, 187 kA at 240 V.
