Technical Data
Phase sequence relays DRR10
measure the sequence of the
phases when being switched on
and switch - if necessary - the
rotation of the eld by changing
2 phases.
The integrated PTC-monitor
protects the motor from over-
heating.
Applications are especially ma-
chines and equipment, that is
operated at variable locations e.g.
at building sites. Pumps, com-
pressors and vacuum cleaners
always run correctly. No more
search for faults or change of
wiring necessary.
