The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 690 V. That kind of SCCR headroom at 415 V tells you it's sized for high-fault industrial distribution panels where upstream transformer capacity is substantial. ## Current derating curve — real-world panel temperature matters Above that, it steps down: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, 56.7 A at 70 °C. If this breaker lands in a sealed, high-density panel near other heat sources, that derating is the number that governs your actual load capacity — not the nameplate 63 A. ## What's on the frame — and what isn't If your spec calls for an auxiliary contact for status feedback or a UVR for safe-start interlocking, you'd need a different variant in the 3VA family.","metaTitle":"Siemens 3VA1163-5EF36-0JA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0JA0 molded case circuit breaker, 3-pole, 63 A, TM240 release, 187 kA at 240 V.
