Breaking capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V. At 690 V the 17 kA rating is modest; if your system runs 690 V with high available fault current, you'll want to verify coordination with the upstream device. The breaker measures 110 mm deep by 138 mm wide by 248 mm tall. The 138 mm width for a 3-pole 630 A frame is standard for the SENTRON 3VA platform; it fits the same mounting footprint as other 3VA breakers in this current class, so a panel laid out for a 3VA2 630 A unit accepts this one without drilling new holes. Maximum power loss is 164.5 W.","metaTitle":"Siemens 3VA2463-5JQ32-0BL0 SENTRON MCCB, 630A 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0BL0 molded case circuit breaker. 630A at 40°C, 3-pole, 187kA breaking at 240V.
