It carries the ETU320 electronic trip unit, which gives you adjustable thermal-magnetic or LSI curves depending on the variant — here it's configured for line protection (overload and short-circuit), not ground-fault or communication. At 415 V and 440 V the breaker still interrupts 121 kA; at 500 V it drops to 75.6 kA, and at 690 V it's 17 kA. ## Thermal derating and endurance If the panel runs hot (say, next to a drive cabinet), check the 55 °C column (384 A) or 60 °C (376 A) to see if you still have headroom for your load. Mechanical endurance is 15,000 operations — fine for a main breaker or infrequent switching, but not for a daily disconnect duty cycle. That depth is shallow enough to fit most standard distribution panels without a deep enclosure. ## Auxiliary contacts and wiring The integrated auxiliary trip (undervoltage release) is order code 3VA9608-0BB24; the basic switch (the breaker itself without auxiliaries) is 3VA2440-5HL32-0AA0. If you're replacing just the breaker core, order the -0AA0 and reuse the aux block.","metaTitle":"Siemens 3VA2440-5HL32-0CL0 SENTRON MCCB, 400A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0CL0 molded case circuit breaker, 400A rated continuous current, 187kA breaking at 240V.
