Product details

MCCB for high-current motor protection

It carries a 187 kA interrupting rating at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 17 kA at 690 V — figures that define its fault-clearing capability at the panel's supply voltage. An integrated undervoltage release (UVR) is fitted as standard; the auxiliary release is the 3VA9608-0BB24 module.

Dimensions are 248 mm high x 138 mm wide x 110 mm deep, designed for panel mounting with busbar or cable connections.

Protection and compliance details

Maximum power loss is 101.5 W; no auxiliary contacts or communication module are included on this variant.

Frequently asked questions

Where can I buy 3VA2450-5MN32-0CA0 and how do I get a price?

This MCCB is sourced to order through our industrial-automation distribution channel. Submit an RFQ; availability and current pricing are confirmed at quote time.

What is the breaking capacity of 3VA2450-5MN32-0CA0 at 415 V?

The interrupting rating is 121 kA at 415 V (and at 440 V); at 240 V it is 187 kA.

Does this MCCB include an undervoltage release?

Yes, the 3VA2450-5MN32-0CA0 ships with an undervoltage release (UVR) as the auxiliary release.

What are the physical dimensions of 3VA2450-5MN32-0CA0?

Height 248 mm, width 138 mm, depth 110 mm.

What is the closest functional second-source to 3VA2450-5MN32-0CA0?

The peer 3VA1112-5EF32-0CA0 is a different SENTRON frame size and rating; it does not drop into the same panel without rewiring. The 3VA2450-5MN32-0CA0 is a 500 A, 3-pole, ETU350M unit — verify the peer's ampere and trip curve before substituting.
