At 415 V and 440 V it still interrupts 242 kA, and at 690 V it holds 52.5 kA, so it's sized for main or tie-breaker duty in industrial switchboards where the available fault current is substantial. ## Current derating and thermal management in the panel The maximum power loss is 162 W, which drives ventilation requirements in a sealed cabinet: at full load that heat has to be moved out, either by natural convection through a properly sized gland plate or by forced air. The 110 mm depth means it clears shallow backpanels, but verify the door clearance for the rotary handle if one is fitted.","metaTitle":"SENTRON 3VA2463-7HL32-0AG0 MCCB, 630 A, 330 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2463-7HL32-0AG0 molded case circuit breaker, 630 A rated current, 330 kA breaking capacity at 240 V, 3-pole, ETU320 release, current production.
