For a panel sitting at 50 °C, you're limited to 593 A continuous; plan the load schedule against the derated number, not the 40 °C sticker. Breaking capacity is where this unit separates from a standard 50 kA MCCB. At 240 V it clears 242 kA; at 415 V and 440 V it holds 187 kA; at 500 V it's still 121 kA; at 690 V it drops to 40 kA. Those numbers mean it handles high-fault-current scenarios — think large transformer secondaries, busway feeds, or industrial mains where the available fault current exceeds 100 kA. The ETU350 electronic trip unit is the brains — it's a microprocessor-based release with adjustable long-time, short-time, and instantaneous protection bands, plus ground-fault capability is absent on this variant (no ground fault monitoring fitted). Latching endurance is rated at 15 000 cycles — sufficient for main feeder duty where the breaker operates infrequently, not for frequent switching.","metaTitle":"Siemens SENTRON 3VA2463-6HN32-0AH0 MCCB, 630 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0AH0 molded case circuit breaker, 630 A rated at 40 °C, 242 kA breaking at 240 V.
