Its breaking capacity runs from 187 kA at 240 V down to 3 kA at 690 V — so at typical 400/415 V industrial feeds it still clears 121 kA, which puts it in the high-interrupting category for a 63 A frame. The 800 V rated insulation voltage means it's comfortable in 480/600 V systems without derating the insulation path. The 3-pole design with line-protection trip curve suits feeder or main breaker duty in a sub-distribution board. At 415 V it's still 121 kA, and at 500 V it drops to 75.6 kA. The steep fall to 3 kA at 690 V is typical for a 63 A frame — if you're on a 690 V system you need to verify the available fault current is under that threshold. For most 400 V industrial plants, 121 kA gives generous headroom above typical transformer-fed fault levels. ## Thermal performance and operating range Rated 63 A continuous without derating across the full ambient range from 40 °C up to 70 °C — that's unusual for an MCCB; most frames start derating above 40 °C. Operating ambient from -25 °C to 70 °C, storage from -40 °C to 80 °C. Maximum power loss is 5.4 W, which is modest for a 63 A electronic-trip breaker.","metaTitle":"Siemens 3VA2063-5KP32-0AF0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5KP32-0AF0 molded case circuit breaker. 63 A continuous, 3-pole, 187 kA breaking at 240 V.
