PUA1 1-Phase AC/DC Over Voltage Monitoring Relay
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.
