Product details

The SENTRON 3VA1340-4EF32-0KD0 is a 3-pole molded case circuit breaker rated 400 A continuous at 40 °C, built for line-protection duty with a TM240 thermal-magnetic release. The TM240 release is thermal-magnetic, so it handles overloads thermally and short-circuits magnetically; no electronic trip unit to program or fail.

Dimensions are 248 mm high, 138 mm wide, 110 mm deep — standard 3-pole MCCB footprint for a 400 A frame.

Rated 400 A from 40 °C up to 50 °C; derates to 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C.

Frequently asked questions

What is 3VA1340-4EF32-0KD0's listed depth?

The depth is 110 mm (4.3 in).

What is 3VA1340-4EF32-0KD0's listed width?

The width is 138 mm (5.4 in).

Will 3VA1340-4EF32-0KD0 drop into a panel specified around 3VA1110-5EF36-0AD0 without rewiring?

Both are 3-pole SENTRON MCCBs, but the 3VA1340-4EF32-0KD0 is a 400 A frame with a TM240 release, while the 3VA1110-5EF36-0AD0 is a smaller-frame unit — verify busbar spacing and lug size before swapping; the footprint and termination may differ.
