That interrupting rating drops to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 9 kA at 690 V — so the SCCR headroom is highest on 208/240 V secondaries, but still substantial on 400/480 V distribution. The breaker's power loss is 162 W at rated load, which matters for enclosure thermal management — especially in a sealed panel with multiple breakers ganged together. That depth (110 mm) is the key clearance dimension for enclosure depth — verify the backpan-to-door clearance accommodates it, especially with the shunt trip wiring and auxiliary switch harnesses dressed behind the breaker. The width (138 mm) for a 3-pole frame is standard for this SENTRON 3VA2 series; it mounts on a mounting plate or DIN rail adapter, not direct snap-on DIN. The auxiliary switch block provides two form-C auxiliary contacts for status feedback, plus a separate trip alarm contact and an electrical alarm contact. No undervoltage release is fitted (that would be a different suffix). No communication module or ground-fault monitoring is included on this variant.","metaTitle":"Siemens 3VA2463-7HN32-0KL0 SENTRON MCCB, 630 A, 3-pole, 330","metaDescription":"Siemens 3VA2463-7HN32-0KL0 SENTRON molded case circuit breaker, 630 A continuous, 3-pole, 330 kA breaking capacity at 240 V.
