Product details

The interrupting capacity reaches 187 kA at 240 V, stepping down to 121 kA at 415/440 V and 75.6 kA at 500 V — at 690 V it still holds 9 kA. That's enough headroom for most industrial distribution panels feeding motor control centers.

What the built-in components mean for a panel swap

That means no extra wiring for a shunt trip or aux contact block — the UVR drops the breaker if control voltage fails, and the alarm switch signals a trip condition back to the PLC or annunciator. Phase failure detection is also built in, so it catches a lost phase before the motor cooks. The auxiliary release is a UVR, not a shunt trip — if your circuit needs a remote trip from a pushbutton or safety relay, you'd add a shunt trip separately.

Frequently asked questions

How do I get current pricing and availability for 3VA2450-5MN32-0CH0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time from independent distribution — no automated figure here is reliable for a buying decision.

What compliance documentation does this breaker carry?

The SENTRON series is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers. Specific certification marks (CE, UL, CSA) are typically listed on the nameplate; the datasheet and declaration of conformity are available from Siemens on request.

Will 3VA2450-5MN32-0CH0 drop into a panel specified around 3VA2116-5JP32-0AE0 without rewiring?

Not directly — the 3VA2450 is a 500 A frame, while the 3VA2116 is a 160 A frame. The physical footprint (width, depth, mounting hole pattern) differs between frame sizes. You'd need to verify panel cutout dimensions and bus bar spacing before assuming a drop-in swap.
