Carlo Gavazzi Monitoring Relay Current/Voltage 1-Phase Plug-In PUA01CD48500V

Carlo Gavazzi Monitoring Relay 1-Phase AC/DC Over Voltage, AC Over Current, Plug-In, SPDT, Supply: 24-48VAC/DC.

DUA01 and PUA01 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.
