It carries an ETU350 electronic trip unit — that's the overcurrent release design, giving you adjustable long-time, short-time, and instantaneous protection curves for coordination downstream. The 187 kA breaking capacity at 240 V means it can safely interrupt fault currents up to that level without cascading upstream; at 415 V and 440 V it still holds 121 kA, and at 690 V it's 17 kA — so the SCCR headroom is there for most industrial distribution panels, but verify the system voltage against your fault current. This is a line-protection version — no ground-fault monitoring, no phase-failure detection, no communication module. What it does have is an undervoltage release (UVR) built in, plus two HQ auxiliary switches (form C, rated for signal feedback to a PLC or status lamp). ## Dimensional fit and panel integration ## Temperature derating — what the 630 A rating actually delivers At 45 °C it's 612 A, at 50 °C it's 593 A, at 55 °C it's 575 A, at 60 °C it's 557 A, at 65 °C it's 538 A, and at 70 °C it's 520 A.","metaTitle":"Siemens 3VA2463-5HN32-0BC0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0BC0 molded case circuit breaker, 630 A rated continuous current, 3-pole, ETU350 release, 187 kA at 240 V.
