Interrupting capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — covering most low-voltage distribution scenarios with substantial fault-current headroom. The basic switch version is 3VA2440-6HL32-0AA0. The 3-pole design fits into existing SENTRON switchboard or distribution panel layouts. Maximum power loss is 63.5 W, which should be factored into enclosure thermal calculations. ## Coordination and Selectivity With a 4800 A frame and adjustable trip unit (minimum 600 A), this MCCB supports selective coordination with downstream breakers in a distribution hierarchy. The trip indicator aids troubleshooting during commissioning or fault events. No communication function or voltage trigger is included — this is a straightforward thermal-magnetic or electronic-trip line protection device without integrated metering or remote trip capability.","metaTitle":"Siemens 3VA2440-6HL32-0AF0 SENTRON MCCB, 400A, 3-Pole, 4800A","metaDescription":"Siemens SENTRON 3VA2440-6HL32-0AF0 molded case circuit breaker, 400A rated, 3-pole, 4800A frame.
