Breaking capacity sits at 187 kA at 240 V and 121 kA at 415 V, so it handles high-fault utility feeds without cascading upstream. At 690 V the rating drops to 3.7 kA — still enough for most 690 V motor circuits, but worth checking against the transformer secondary fault level if that is your service voltage. ## Motor protection fit This is a motor-protection MCCB, not a plain distribution breaker. It includes phase failure detection and is designed to track motor thermal characteristics. The adjustable time-delay range (4 s minimum to 17 s maximum) lets you coordinate with the motor start profile and downstream contactor so nuisance trips do not pull the line down during a normal start. Power loss is 4 W maximum, which keeps the enclosure heat rise low when multiple breakers are ganged on a DIN rail. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a 3-pole frame that fits standard SENTRON 3VA2 panel cutouts and busbar systems. Operating range is -25 °C to 70 °C, storage from -40 °C to 80 °C, so it survives unheated warehouses and hot control rooms alike.","metaTitle":"Siemens 3VA2163-5MN32-0KC0 SENTRON MCCB, 63 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2163-5MN32-0KC0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 3-pole, motor protection design with phase failure detection. 187 kA at 240 V.
