Breaking capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That kind of headroom means it can sit upstream of a high-fault panel without worrying about cascading failure. It's designed for motor protection (the product designation says so), and it includes phase failure detection and a communication function — so it can talk to a PLC or BMS about what's happening on the line. That's useful when you need to know a phase dropped before the motor starts single-phasing. ## Sizing and fit in the enclosure Width is the usual 3-pole MCCB pitch; it'll sit on a DIN rail or bolt directly to the mounting plate.","metaTitle":"SENTRON 3VA2163-5MQ32-0AB0 MCCB, 63 A, 3-Pole, 187 kA","metaDescription":"SENTRON 3VA2163-5MQ32-0AB0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA breaking at 240 V.
