Product Description Ordering Key
DUA 01 C B23 500V
DUA01 and PUA01 are pre- cise AC/DC over voltage monitoringrelays. They can also be used as 1-phase or
3-phase over currentmoni- toring relays when connect- edwithMIorMPcurrent
transformers.
Owing to the built-in latch function, the ON-position of the relay output can be maintained.
The redLED indicatesthe alarm status.
