The interrupting capacity tracks the system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. At 690 V the available fault current must be verified against the 9 kA limit — common in 690 V mining or marine distribution where upstream transformers can deliver higher prospective fault levels. ## Shunt trip and communication — what the order code suffix carries Maximum power loss is 162 W at rated current — account for that heat in the enclosure ventilation calculation, especially when multiple breakers are ganged in a switchboard section. ## Panel fit — dimensions and mounting Dimensions: 248 mm height, 138 mm width, 110 mm depth.","metaTitle":"SENTRON 3VA2463-6JQ32-0HA0 MCCB, 630 A, 3-Pole, Line Protect","metaDescription":"SENTRON 3VA2463-6JQ32-0HA0 molded case circuit breaker, 630 A frame, 3-pole, line protection. 242 kA at 240 V.
