Maximum current is 4800 A, with a minimum setting of 600 A, giving flexibility for downstream coordination. That 110 mm depth (4.33 in) is the dimension that matters for enclosure depth. ## Auxiliary switching and power loss This order code includes four HQ auxiliary switches (design of the auxiliary switch: 4 auxiliary switches HQ), which give status feedback for remote monitoring or PLC inputs — useful for tracking breaker state without climbing into the panel. The breaker has no communication function or trip indicator, so it's a straightforward thermal-magnetic or electronic trip unit (the spec doesn't specify the trip type, but the line protection designation suggests an electronic trip for the 400 A frame).","metaTitle":"Siemens 3VA2440-7HL32-0AE0 SENTRON MCCB, 400A, 4800A max","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0AE0 molded case circuit breaker, 3-pole, 400 A at 40 °C, breaking capacity 330 kA at 240 V.
