Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and 75.6 kA at 500 V, so it handles high-fault service-entrance or distribution positions where upstream coordination demands a stiff short-circuit rating. The line-protection design means it's configured for feeder and main breaker duty, not motor-circuit protection — pair it with a separate overload relay for motor starts. ## Integration notes: footprint and release The basic switch assembly is order code 3VA20635KP320AA0, so if you're stocking spares, that's the internal mechanism to keep on the shelf. The interrupting rating drops as line 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.","metaTitle":"Siemens 3VA2063-5KP32-0CA0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5KP32-0CA0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA breaking at 240 V.
