That trip range is what decides whether this breaker fits your feeder or main; if your calculated fault current or load current falls outside that window, this isn't the variant. Short-circuit breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. At 415 V — common for industrial distribution in many regions — 187 kA gives you substantial headroom for high-fault panels. Thermal derating is published from 40 °C through 70 °C: full 400 A holds up to 50 °C, then drops to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. The 96 W maximum power loss also matters for enclosure thermal management. ## Integration and accessories This is a 3-pole breaker in a frame sized 248 mm high, 138 mm wide, 110 mm deep — standard SENTRON 3VA2 form factor for panel mounting. The basic switch variant underneath is 3VA2340-6KP32-0AA0; the -0KC0 suffix adds the communication function, so you get a breaker that can talk to a higher-level system for monitoring or remote operation. Line protection design means the internal trip characteristics are shaped for feeder and main applications, not motor protection.","metaTitle":"Siemens 3VA2340-6KP32-0KC0 SENTRON MCCB, 400 A, 600–4000 A t","metaDescription":"Siemens 3VA2340-6KP32-0KC0 SENTRON molded case circuit breaker, 400 A continuous, adjustable trip 600–4000 A, 242 kA at 240 V.
