That flat thermal curve is unusual; most MCCBs start to derate above 40 °C, so this one buys you headroom in a hot panel or a NEMA 12 enclosure with other heat sources. The interrupting ratings tell you where it clears faults without blowing apart: 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 matters for coordination: you can shape the time-current curve to ride through motor inrush or to selectively coordinate with downstream breakers, which a thermal-magnetic can't do as precisely. This is a line-protection MCCB for the SENTRON series — designed for the incoming feeder or main distribution in a panelboard or switchboard. It's a 3-pole device, sized for a 63 A feeder, and the 86 mm depth, 105 mm width, 181 mm height footprint fits the standard SENTRON mounting base. Power loss is listed at 5.4 W maximum — that's the heat the breaker dumps into the enclosure at full rated current. For a 63 A MCCB that's modest; you won't need forced ventilation for a single unit, but cluster several in a small enclosure and the cumulative heat matters for the ambient derating curve.","metaTitle":"Siemens SENTRON 3VA2063-5HN32-0AA0 MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HN32-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA at 240 V.
