Product Description
DUA01 and PUA01 are pre-
cise 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 main-
tained.
The red LED indicates the
alarm status.
