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. The 63 A frame holds its rating flat from 40 °C through 70 °C ambient, which simplifies panel sizing in a warm enclosure without a derate factor.
Auxiliaries and communication
Factory-fitted with 2 auxiliary switches plus 1 trip alarm switch (HQ type) and a shunt trip release (STL). 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. No undervoltage release or ground-fault monitoring on this order code.
Lifecycle and sourcing
Listed as current production — no phase-out or last-time-buy notice on record. This is a qualified BOM part for OEM builds and MRO spares that need a stable supply horizon. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Dimensions and panel fit
Footprint is 105 mm wide by 181 mm tall, 86 mm deep — standard 3-pole MCCB envelope for DIN-rail or screw-mount panel integration. The 86 mm depth leaves clearance for a standard gland plate and wiring gutters without a deep enclosure.
