The Siemens SENTRON 3VA2163-5JP32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 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 V AC and still delivers 121 kA at 415/440 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream.
Breaking capacity and thermal performance
At 500 V the interrupting rating is 75.6 kA; at 690 V it drops to 3.7 kA — the arc extinction limits at higher voltage define the application ceiling.
Auxiliaries and communication
The communication function is present on this variant, so it can report status and trip events to a control system without an add-on module.
This is a qualified BOM part for OEM builds and MRO spares that need a stable supply horizon.
