The Siemens SENTRON 3VA2163-5JQ32-0CL0 is a 3-pole molded case circuit breaker (MCCB) with a 63 A frame and an adjustable thermal-magnetic trip unit covering 95 A to 756 A. It delivers a breaking capacity of 187 kA at 240 V AC, tapering to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so at typical 400 V distribution voltages it clears fault currents up to 121 kA without cascading upstream.
Thermal performance and panel fit
The 86 mm depth × 105 mm width × 181 mm height footprint fits standard MCCB panel cutouts; the 3-pole block occupies a single DIN-rail or screw-mount position. Power loss is 6.5 W maximum, manageable in a sealed cabinet without forced ventilation.
