Breaking capacity is where this breaker earns its keep in a distribution board. At 240 V it interrupts 330 kA; at 415 V and 440 V it holds 242 kA; at 500 V still 187 kA. Only at 690 V does it drop to 9 kA — that's the limit of the internal arc chamber. For most 400 V class switchgear these numbers give generous SCCR headroom for selective coordination upstream of branch feeders. ## Built-in accessories and wiring The basic switch core is the 3VA2440-7HL32-0AA0 — the accessory pack adds the remote-trip and status-reporting hardware without needing a separate kit. Maximum power loss is 63.5 W at full rated current. That's moderate for a 400 A frame — plan for ventilation if the breaker is enclosed in a small glanded box, but in a standard switchboard it dissipates fine through the mounting plate.","metaTitle":"Siemens 3VA2440-7HL32-0HH0 SENTRON MCCB, 400 A, 600–4800 A t","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0HH0 molded case circuit breaker, 400 A rated, adjustable trip 600–4800 A, 3-pole, 110 mm deep.
