The Siemens SENTRON 3VA2163-5MN32-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — figures that govern selectivity coordination in high-fault panels.
The basic switch part number is 3VA21635MN320AA0.
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.
