The Siemens SENTRON 3VA2463-7HN32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a massive 330 kA interrupting capacity at 240 VAC. That breaking capacity drops to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V — so the real-world SCCR you can count on depends on your system voltage. The 630 A frame means this breaker handles main feeder or large motor protection duty in a 480 V panel, not branch circuits.
Continuous current derates with ambient temperature: 630 A at 40 °C, 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. The 164.5 W maximum power loss matters for enclosure thermal management; that's heat that stays inside the panel. At 480 V (not explicitly listed, but between the 440 V and 500 V figures), you can interpolate roughly 200–220 kA — still very high, suitable for main service entrance or high-fault industrial distribution.
That gives you remote status indication — breaker on/off, trip event, and a separate alarm contact for the protection trip. The UVR means the breaker drops out when control voltage is lost, which is standard for safety circuits or emergency-off chains.
Dimensions: 248 mm height, 138 mm width, 110 mm depth. The 3-pole footprint is what you'd expect for a three-phase feeder breaker.
