The Siemens 3VA1163-4EF32-0BC0 is a 3-pole SENTRON molded case circuit breaker rated for 63 A continuous current (Iu) at 40 °C, with a TM240 thermal-magnetic trip unit. Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — that's enough to clear a high-fault utility feed without cascading upstream.
The auxiliary trip module (3VA9608-0BB11) is a separate order; verify it's included or ordered alongside if the BOM calls for shunt-trip capability.
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.
121 kA at 240 V, which covers high-fault utility feeds and transformer secondaries without needing a current-limiting fuse upstream.
Yes, an undervoltage release (UVR) is built in as standard on this variant.
