What this 3VA2163-7HN32-0JC0 brings to the panel
The Siemens SENTRON 3VA2163-7HN32-0JC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which matters when the breaker sits in a warm cabinet next to other heat sources. Its interrupting capacity hits 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V — numbers that put it squarely in the high-fault category for industrial distribution where available short-circuit current is substantial. The breaker ships with a shunt trip (STL) release and two auxiliary switches HQ built in, so it arrives ready for remote tripping and status feedback without ordering add-on modules separately.
Footprint and panel fit
At 105 mm wide, 181 mm tall, and 86 mm deep, this 3-pole MCCB fits the standard SENTRON 3VA2 panel cutout — the same footprint as other 63 A frames in the series, so a swap from a different 3VA2 variant means no re-drilling or busbar rework. The base switch is 3VA2163-7HN32-0AA0; the -0JC0 suffix adds the shunt trip and auxiliary switches at the factory, saving a wiring step on the panel build.
