At 690 V the interrupting capacity drops to 9 kA, so if your system runs at 690 V, this breaker is only suitable for low-fault locations. The thermal-magnetic trip unit has an adjustable Ir (continuous current setting) from 126 A to 630 A, so you can fine-tune it to match the actual load — a 400 A feeder, for instance, can be set without swapping the frame. The full-scale value is 630 A. Temperature derating is built in: at 45 °C the continuous rating is 612 A, at 50 °C it is 593 A, and at 70 °C it drops to 520 A. The maximum power loss is 162 W, so ventilation in the enclosure matters. This MCCB is designed for fixed mounting in a distribution panel or switchboard. No DIN-rail clip; it bolts directly to the panel backplate or busbar system. The depth of 110 mm means it clears most standard enclosure doors with room for cable bending.","metaTitle":"Siemens 3VA2463-5HM32-0AA0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5HM32-0AA0 molded case circuit breaker, 630 A continuous, 187 kA at 240 V, 3-pole, line protection, ground-fault summation.
