Its 187 kA interrupting capacity at 240 VAC — and 121 kA at both 415 V and 440 V — gives it the headroom to clear high-fault scenarios without cascading upstream, which is the deciding factor when coordinating selectivity in an existing switchboard. The breaker carries a flat thermal derating curve: the full 63 A holds from 40 °C all the way to 70 °C, so you don't lose capacity in a warm enclosure. The 3VA2063-5HL32-0AB0's breaking capacity drops off as system voltage rises: 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. The 690 V figure is low — verify your available fault current if this breaker lands on a 690 V bus. The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that drops into existing DIN-rail or panel-mount layouts without re-drilling. The 800 V rated insulation voltage means it's comfortable on 480/277 V and 600 V systems with margin.","metaTitle":"Siemens 3VA2063-5HL32-0AB0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HL32-0AB0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA breaking capacity at 240 VAC.
