What this MCCB carries and where it fits
The Siemens SENTRON 3VA2163-5KP32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 187 kA at 240 VAC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault industrial services where the available short-circuit current is substantial. Designed for line protection, it includes an undervoltage release (UVR) and two auxiliary switches (HQ type), plus a communication function and other measurement capability — meaning it can report status and trip events back to a control system without a separate interface module.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard SENTRON 3VA frame size that drops into a DIN-rail or screw-mounted panel footprint common across the series. The 63 A frame and 3-pole block leave room for side-mounted auxiliary blocks and the UVR coil without crowding adjacent breakers. Power loss is 6.5 W maximum, manageable in a closed enclosure with basic ventilation.
