The Siemens SENTRON 3VA2063-6HN32-0KH0 is a 3-pole molded case circuit breaker rated for 63 A continuous current, with a breaking capacity of 242 kA at 240 V and 187 kA at 415 V — numbers that put it in the high-interrupting tier for industrial distribution, not a general-purpose feeder breaker.
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a 3-pole 3VA2 frame that mounts on a DIN rail or screws directly to a backplate. At 86 mm depth, it fits enclosures with room for rear-connected busbars or cable lugs.
Trip unit and auxiliary wiring
Maximum power loss is 5.4 W, so thermal rise in a crowded panel is manageable — no forced cooling required for the breaker itself.
