That SCCR means it can sit upstream of a 240 V distribution panel without worrying about cascading failure — the breaker clears a fault before the arc flash energy climbs. The undervoltage release (UVR) is built in, so if the control voltage drops, the breaker trips. That's a standard safety interlock for conveyor or pump circuits where a loss of control power should kill the motor feed. The 630 A frame is line-protection design (not motor-protection), so the thermal-magnetic curve is set for cable and busbar protection, not motor overload. If you're replacing a motor-protection breaker, check the trip curve before swapping. ## Breaking capacity across voltages — selectivity planning The 3VA2463-7HL32-0DA0 delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. That drop at 690 V is typical for a 630 A frame — the arc extinction energy limits the high-voltage interruption. The 240 V and 415 V ratings give generous selectivity headroom for most industrial distribution boards. ## Current derating — thermal environment matters Rated 630 A at 40 °C, but this breaker derates linearly as ambient rises: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. Plan the load at the actual ambient, not the nameplate 630 A.","metaTitle":"Siemens 3VA2463-7HL32-0DA0 SENTRON MCCB, 630 A, 3-Pole, UVR","metaDescription":"Siemens SENTRON 3VA2463-7HL32-0DA0 molded case circuit breaker, 630 A at 40 °C, 3-pole, 330 kA at 240 V.
