The headline number here is the interrupting capacity: 187 kA at 240 V AC and 121 kA at 415 V AC — that puts this breaker in the high-fault-current tier, sized for main or feeder positions where upstream transformer capacity or utility fault levels would blow past a standard 25 kA or 36 kA MCCB. At 690 V it still holds 17 kA, so it works in 480/277 V or 600 V industrial systems without derating the interrupt rating below the available fault current. The 70 mm depth and 76.2 mm width fit the standard SENTRON 3VA footprint, meaning it drops into existing panel layouts that already carry 3VA breakers. ## Thermal derating and release design — TM240 with undervoltage trip It holds 63 A straight up to 50 °C, then steps down to 60.48 A at 55 °C and 56.7 A at 70 °C. Two HQ auxiliary switches are built in, giving status feedback for the open/closed position without needing an add-on module. ## Panel integration — IP40 front, DIN-rail or screw-mount","metaTitle":"Siemens 3VA1163-5EF36-0CC0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA1163-5EF36-0CC0 SENTRON molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V.
