The interrupting ratings climb to 330 kA at 240 V and hold at 242 kA through 440 V, then step to 187 kA at 500 V and drop to 9 kA at 690 V. The ETU320 electronic trip unit gives adjustable long-time, short-time, instantaneous, and ground-fault protection — it's a programmable curve, not a fixed thermal-magnetic. That 184 mm width across 4 poles is standard for a 400 A frame — it occupies the same footprint as other SENTRON 3VA 4-pole breakers in this current class. The 110 mm depth leaves clearance for rear-connected busbars or cable lugs in a typical switchboard section. ## Selectivity and coordination notes With a minimum trip setting of 600 A and maximum of 4 800 A (via the ETU320), this breaker can be selectively coordinated downstream of a larger main or upstream of distribution MCCBs.","metaTitle":"Siemens 3VA2440-7HL42-0AA0 SENTRON MCCB, 400 A, 4-Pole, 330","metaDescription":"Siemens 3VA2440-7HL42-0AA0 SENTRON molded case circuit breaker, 400 A continuous, 4-pole, ETU320 release, 330 kA at 240 V.
