Breaking capacity is the headline spec here: 220 kA at 240 VAC, 154 kA at 415 V, and 121 kA at 440 V. At 500 V and 690 V the rating drops to 7.5 kA — still sufficient for most industrial motor branch circuits at those voltages, but the sharp knee means this breaker is optimised for 400 V-class distribution where high fault current is the norm. Dimensions are 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). The auxiliary switch configuration — 1 auxiliary switch + 1 trip alarm switch HQ — is factory-integrated, so no add-on module occupies additional DIN space. Power loss at rated load is 17.3 W maximum, which factors into enclosure thermal calculations for non-ventilated stainless-steel panels. ## Compliance & Documentation As a SENTRON-series MCCB, the 3VA1163-6MH32-0AF0 is designed and tested to IEC 60947-2 and UL 489 standards for molded case circuit breakers. The TM120M thermal-magnetic release provides fixed thermal and fixed magnetic trip settings, with a trip indicator on the front face for visual status.","metaTitle":"3VA1163-6MH32-0AF0 SENTRON MCCB, 63 A, 220 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1163-6MH32-0AF0 molded case circuit breaker, 63 A rated, 220 kA breaking capacity at 240 VAC.
