The breaking capacity is the headline number for fault protection: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. ## Integration — what fits where The depth of 86 mm means it clears most standard enclosure depths, but check gland-plate clearance if the panel is shallow. The auxiliary contact version is 3 auxiliary switches HQ, and the integrated auxiliary trip is order code 3VA9608-0BB24. The supplied basic switch is 3VA2163-7MS32-0AA0. ## Overcurrent release and trip unit The overcurrent release is the ETU310M — an electronic trip unit with adjustable settings for motor protection. The trip indicator is not present, so a remote indication of trip status would need to come from the auxiliary switches. Phase failure detection is not built in, but the ETU310M typically handles phase unbalance through its thermal model. ## Environmental limits Mechanical endurance is 20,000 operations.","metaTitle":"Siemens 3VA2163-7MS32-0AD0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0AD0 molded case circuit breaker, 63 A rated, 330 kA breaking at 240 V.
