The real-world selection number is the thermal derating: at 40 °C it carries the full 630 A, but at 50 °C you're down to 570 A, and at 70 °C it's 450 A. The interrupting ratings are given per voltage: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. For 400 V class panels, the 187 kA figure gives plenty of headroom for most industrial services. ## Built-in auxiliary and alarm switches, shunt trip That means you can wire remote status indication and a remote trip signal without buying add-on modules. The basic switch assembly is order code 3VA2463-6JQ32-0AA0 — if you're replacing just the switch mechanism, that's the part to pull. ## Panel fit and power loss Maximum power loss is 162 W at full load, so factor that into the enclosure thermal budget.","metaTitle":"Siemens 3VA2463-6JQ32-0KL0 SENTRON MCCB, 630 A, 3-pole, 242","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0KL0 molded case circuit breaker, 630 A, 3-pole, breaking capacity 242 kA at 240 V.
