Power loss is 6.5 W maximum, which keeps heat rise manageable in a densely packed enclosure. Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — the 105 mm width is standard for a 3-pole MCCB in the SENTRON 3VA frame, so it fits existing panel cutouts and busbar spacing without modification. The trip indicator is present, giving a local visual signal after a fault event — useful for troubleshooting without a connected communication system.","metaTitle":"3VA2163-5KP32-0CH0 SENTRON MCCB, 63 A, 3-Pole, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-5KP32-0CH0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA breaking capacity at 240 VAC.
