Product details

MCCB with motor-protection design and electronic release

Its ETU350M electronic release is designed for motor protection with adjustable trip classes 10A, 10E, and 20E.

Sizing and selectivity for the panel builder

At 86 mm deep, 105 mm wide, and 181 mm tall, the 3VA2140-0MN32-0AA0 fits the standard SENTRON 3VA footprint — it occupies the same panel cutout as other 3VA frame breakers, so a panel laid out for a 3VA2040 or 3VA2140 sibling accepts this unit without re-drilling. The IP40 protection on the front face is typical for enclosed panel mounting; the breaker is not intended for exposed outdoor installation without an additional enclosure. Phase failure detection is built into the ETU350M release, so no external phase-loss relay is needed for motor circuits.
