The interrupting ratings climb with the voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That UVR is a must-have for any safety circuit that drops the breaker when control power is lost — think emergency-stop chains or undervoltage protection on a motor feeder. The communication function means it can talk to a higher-level system for remote monitoring or trip-event logging, which saves a walk to the panel when you're trying to figure out what tripped. The depth of 86 mm leaves room for cable bending space behind the breaker in a typical 200 mm deep enclosure. Power loss is rated at a maximum 7.9 W. That's low enough that you don't need to sweat heat buildup in a densely packed panel, but it's still worth accounting for when you're doing a thermal calculation on a multi-breaker lineup.","metaTitle":"Siemens SENTRON 3VA2063-5JQ32-0CL0 MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0CL0 molded case circuit breaker. 63 A rated current, 3-pole, 187 kA breaking capacity at 240 V.
