The Siemens SENTRON 3VA2163-6HN36-0CC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. Breaking capacity hits 242 kA at 240 V AC, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 3.7 kA at 690 V.
Many breakers in this class start derating above 40 °C; this one holds its full ampacity, so it's a good pick for a crowded panel or a hot environment like a motor control center near a furnace line.
That saves panel-build time — no separate ordering or field-fitting of the UVR coil. The auxiliary switches give remote status indication for the breaker position (open/closed/tripped), which is useful for a PLC input or a status lamp on the door. Verify the UVR coil voltage rating against your control supply before wiring.
Physical fit
The 86 mm depth (3.39 in) fits most enclosures.
