The adjustable thermal-magnetic trip unit covers 600 A minimum to 4 800 A maximum, giving the specifying engineer flexibility to match the breaker to the actual load without swapping the frame. Breaking capacity is 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V — the high interrupt ratings at common distribution voltages make this a strong candidate for main or feeder protection in high-fault-current panels. The 3VA2 platform uses a common footprint across the current range, so a panel designed for a lower-rated 3VA2 can accept this 400 A unit without re-drilling the mounting plate or re-spacing the bus bars. The base switch variant is 3VA2440-7HL32-0AA0; the -0HC0 suffix adds the shunt trip and dual auxiliary switches as factory-integrated options.","metaTitle":"Siemens 3VA2440-7HL32-0HC0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0HC0 molded case circuit breaker, 400 A continuous, 600-4800 A adjustable trip, 330 kA at 240 V.
