The continuous current is fixed at 63 A by the frame and thermal elements; the 189–945 A band sets the magnetic trip level for motor-starting inrush. It measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into the same DIN-rail or panel-mount space as other SENTRON 3VA2 breakers. The depth of 86 mm leaves room for rear busbar connections in a shallow backpanel. ## Environmental limits The 4 W maximum power loss is low enough that you don't need to derate adjacent devices in a packed panel.","metaTitle":"Siemens 3VA2163-7MS32-0AC0 SENTRON MCCB, 3-Pole, 63 A, 330 k","metaDescription":"Siemens 3VA2163-7MS32-0AC0 SENTRON molded case circuit breaker, 3-pole, 63 A continuous, interrupting up to 330 kA at 240 V.
