Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. That's a high-interrupting rating — suitable for installations with high available fault current, like large distribution panels or transformer secondaries. It also includes a voltage-trip indicator and a mechanical trip indicator. The basic switch inside is order code 3VA2440-5HN32-0AA0. Maximum power loss is 63.5 W, so plan for that heat rejection inside the enclosure, especially if several breakers are ganged. That covers most indoor and sheltered outdoor installations without special enclosures.","metaTitle":"Siemens 3VA2440-5HN32-0HL0 SENTRON MCCB, 400 A, 4800 A rated","metaDescription":"Siemens SENTRON 3VA2440-5HN32-0HL0 molded case circuit breaker, 400 A, 4800 A rated current, 187 kA at 240 V, 3-pole, line protection.
