The continuous current derates predictably as ambient climbs: 612 A at 45 °C, 593 A at 50 °C, down to 520 A at 70 °C, so if your panel runs hot, the actual ampacity drops. ## Panel fit and mounting constraints The breaker occupies 184 mm width, 248 mm height, and 110 mm depth — that's 7.24 by 9.76 by 4.33 inches. It's a DIN-rail or direct-panel mount, typical for SENTRON 3VA frames at this current level. The 4-pole configuration means it needs four phase connections plus neutral if the system requires it. The shunt trip (STL) and auxiliary switches are factory-fitted, so no field wiring of separate accessories — just land the power conductors and the control wires for the shunt trip coil and the auxiliary contact outputs. Verify the panel depth clears the 110 mm plus wiring space behind the breaker. ## Breaking capacity by voltage — selectivity planning The interrupting capacity drops sharply above 500 V: 75.6 kA at 500 V, then only 9 kA at 690 V. For 240 V and 415 V systems it's extremely capable (187 kA and 121 kA respectively), so it's a strong choice for the main breaker in a 480Y/277 V panel where the available fault current is high. The minimum trip setting is 945 A, maximum 5 670 A, which gives you a wide adjustment range for coordination with downstream devices.","metaTitle":"Siemens 3VA2463-5HL42-0KK0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2463-5HL42-0KK0 molded case circuit breaker, 630 A continuous at 40 °C, 187 kA breaking at 240 V, 4-pole line protection.
