Product details

At the common 415 V / 440 V industrial distribution level it delivers 121 kA — high enough to back a transformer-fed main without a current-limiting fuse upstream in most installations.

Auxiliary and undervoltage release configuration

Factory-fitted with two HQ auxiliary switches and an undervoltage release (UVR). The HQ auxiliary contacts provide status feedback for the PLC or DCS without adding a separate contactor block.

Footprint is 138 mm wide by 248 mm tall by 110 mm deep.

Phase-failure detection is built in, and the design includes undervoltage release as standard — two features that matter for motor protection on three-phase feeders where a lost phase can single-phase the load.

Frequently asked questions

What is 3VA2440-5MN32-0BC0's listed depth and width?

Depth is 110 mm and width is 138 mm, matching the standard SENTRON 3VA4 frame size.

Will 3VA2440-5MN32-0BC0 drop into a panel specified around 3VA2225-5HN42-0BB0 without rewiring?

The 138 mm width is identical between the two frames, so the bus-bar drill pattern and enclosure cutout are the same. However, the 3VA2440 is a 400 A frame versus the lower-current 3VA2225 — verify that the bus bars and cable terminations are rated for 400 A before substitution.
