Carlo Gavazzi DUA01 / PUA01 Monitoring Relay

The Carlo Gavazzi DUA01 / PUA01 monitoring relay’s are precise AC/DC over voltage monitoring relays. They can also be used as 1-phase or 3-phase over current monitoring relays when connected with MI or MP current transformers. Owing to the built-in latch function, the ON-position of the relay output can be maintained. The red LED indicates the alarm status.
