Frame maximum is 4800 A, so this is a 400 A trip unit in a frame that can handle much higher fault currents. Short-circuit breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. ## Shunt trip and line-protection design The base switch is the 3VA2440-7HL32-0AA0; this order code adds the shunt trip. No communication function, no auxiliary switch fitted — this is a straightforward distribution breaker with remote trip capability. Width of 138 mm (5.43 in) and depth of 110 mm (4.33 in) mean it fits a typical MCCB slot in a distribution board. Height of 248 mm (9.76 in) is the tallest dimension — check clearance above the busbar chamber. No derating needed across the full operating range for this 400 A rating.","metaTitle":"Siemens 3VA2440-7HL32-0HA0 SENTRON MCCB, 400 A, 4800 A max,","metaDescription":"Siemens 3VA2440-7HL32-0HA0 SENTRON 3-pole molded case circuit breaker, 400 A continuous, 4800 A max frame, 330 kA at 240 V.
