At 690 V the interrupting rating drops to 52.5 kA; size the SCCR study against that number if your line runs at 690 V. ## Derating and thermal budget Rated 630 A at 40 °C ambient, but the continuous current derates linearly to 450 A at 70 °C — a 180 A swing that matters in a hot enclosure or near other high-draw gear. Maximum power loss is 162 W; factor that into the panel's thermal dissipation budget, especially if the breaker shares a compartment with drives or transformers. Footprint is 184 mm wide × 248 mm high × 110 mm deep — a 4-pole frame that needs a full-width cutout in the gland plate. The 110 mm depth fits within a standard enclosure depth.","metaTitle":"Siemens SENTRON 3VA2463-8JQ42-0AA0 MCCB, 630 A, 440 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-8JQ42-0AA0 molded case circuit breaker, 4-pole, 630 A, ETU560 trip unit, 440 kA at 240 V.
