The Siemens SENTRON 3VA2163-5KP32-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current with an insulation voltage of 800 V. It's designed for line protection in industrial distribution panels, and the interrupting ratings are the headline numbers here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V means it can safely clear a fault up to that level without the arc flashing over or the case rupturing — critical for high-fault-capacity services like a transformer secondary or a large motor control center. The breaker carries a communication function (likely for remote monitoring or trip indication) and comes with one auxiliary switch plus one trip alarm switch (HQ type) factory-installed.
Mounting & Integration
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. It mounts into a standard panel or enclosure footprint for 3-pole MCCBs of this frame size. The auxiliary and alarm switch wiring lands on the integrated terminal block; verify the switch configuration matches your monitoring scheme before wiring.
Ratings & Selectivity
The 63 A rating holds from 40 °C to 70 °C. Minimum trip setting is 95 A, maximum is 756 A. Insulation voltage is 800 V.
