The interrupting ratings are substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. Thermal derating is explicit across the operating range: the breaker carries its full 630 A at 40 °C, but this drops to 600 A at 45 °C, 570 A at 50 °C, and continues down to 450 A at 70 °C. When sizing for a warm panel or high-ambient environment, use the derated value — not the 630 A nameplate — to avoid nuisance tripping. ## Trip Unit and Adjustability The electronic trip unit is adjustable between a minimum of 945 A and a maximum of 5 670 A, with an initial setting of 126 A. This wide range allows coordination with downstream breakers and load characteristics. Note that the trip indicator is not fitted on this variant, so a separate indication method is needed for fault diagnosis. No undervoltage release or auxiliary release is fitted as standard. The 110 mm depth is a key check for shallow enclosures or when mounting behind a gland plate. Panel builders should verify the depth clearance against the enclosure door and any busbar or cable ducting behind the breaker. Maximum power loss is 162 W at rated current. This heat must be dissipated within the enclosure; factor it into the thermal design of the panel, especially if multiple breakers are ganged or the enclosure is sealed.","metaTitle":"Siemens SENTRON 3VA2463-6JQ32-0AB0 MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0AB0 molded case circuit breaker, 630 A, 3-pole, line protection.
