This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. That 330 kA at 240 V is the headline number — it means this breaker can interrupt a fault current up to 330,000 amps at that voltage without welding or rupturing. For a 63 A frame, that's enormous headroom, which makes it useful downstream of large transformers or in high-fault-capacity industrial services where you need to maintain selectivity with upstream gear. The 690 V rating drops to 3 kA, so if you're on a 690 V system, you're limited to relatively low available fault current. Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. ## Temperature derating and ratings The 63 A continuous rating holds flat from 40 °C through 70 °C ambient (–) — no derating needed in a warm panel, which is a practical advantage. Rated insulation voltage is 800 V, so it's suitable for 480 V and 600 V class systems with margin. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Power loss is 3 W maximum, negligible for panel heat calculations.","metaTitle":"Siemens 3VA2063-7KP32-0AA0 SENTRON MCCB, 63 A, 3-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2063-7KP32-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, ETU850 trip unit.
