It carries a 440 kA interrupting capacity at 240 V AC, dropping to 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Panel integration is straightforward: the 105 mm width fits standard Siemens SENTRON mounting patterns, and the 181 mm height with 86 mm depth leaves room for cable bending radius in a typical 600 mm deep enclosure. Power loss is a modest 3.1 W maximum, so heat buildup in a dense lineup is manageable. ## Peer Comparison — 3VA2163-8HM32-0AA0 The closest functional sibling is the 3VA2163-8HM32-0AA0. Both are 3-pole, 63 A, SENTRON MCCBs with the same frame size and interrupting ratings. The difference is the trip unit: the -8HN32 carries the ETU350 (electronic, adjustable), while the -8HM32 uses a thermal-magnetic trip. If your coordination study calls for electronic selectivity or adjustable short-time delay, the -8HN32 is the correct choice. If the panel was specified around the -8HM32, the -8HN32 drops into the same mounting footprint and bus connections without rewiring — just verify the trip curve matches your protective device coordination.","metaTitle":"Siemens SENTRON 3VA2163-8HN32-0AA0 MCCB, 63 A, 440 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-8HN32-0AA0 molded case circuit breaker, 3-pole, 63 A continuous, ETU350 trip unit, 440 kA breaking at 240 V.
