What this MCCB carries
The Siemens 3VA2163-5JP32-0AG0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection in 3-pole configuration. Continuous current is 63 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, with a sharp fall to 3.7 kA at 690 V. That 187 kA figure at 240 V means it handles high-fault scenarios typical in North American panel feeds without cascading upstream. Insulation voltage is rated 800 V.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — standard 3-pole MCCB footprint for a 63 A frame. It ships with one auxiliary switch and one trip alarm switch (HP design), plus a communication function for remote status or trip indication. No undervoltage release or ground-fault monitoring on this variant. The trip indicator is present, so you get local visual confirmation of a fault event.
