At 50 °C it derates to 593 A, at 60 °C to 557 A, and at 70 °C to 520 A — if your panel runs hot inside, the actual continuous current you can pull is lower than the nameplate says. Maximum power loss is 162 W — that heat has to leave the enclosure, so factor it into the panel thermal budget, especially in a sealed cabinet. ## Trip unit and protection features Neutral protection is adjustable: OFF, 50%, or 100% of the phase current, set via a dial on the trip unit.","metaTitle":"Siemens 3VA2463-0HL42-0AA0 SENTRON MCCB, 630 A, 4-Pole","metaDescription":"Siemens SENTRON 3VA2463-0HL42-0AA0 molded case circuit breaker, 630 A rated current, 4-pole, ETU320 trip unit, 440 kA at 415 V.
