It ships with a factory-installed shunt trip (STL) release and two auxiliary switches (HQ configuration), so you get remote tripping capability and status feedback without additional wiring. The shunt trip lets a safety PLC or emergency-stop circuit cut power remotely — useful in automated lines where a downstream fault needs to isolate the breaker. ## Thermal derating and power loss Above that, the breaker derates linearly: 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. Maximum power loss is 162 W, which factors into enclosure thermal calculations. Physical footprint: 138 mm wide, 248 mm tall, 110 mm deep. Depth of 110 mm includes the operating mechanism and terminal covers; allow clearance for cable bending radius and the shunt trip wiring.","metaTitle":"Siemens SENTRON 3VA2463-7HL32-0KC0 MCCB, 630 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2463-7HL32-0KC0 molded case circuit breaker, 630 A continuous, 3-pole, 330 kA breaking at 240 V.
