RMQ-121D Overexcitation Relay

This relay is applied to protect a generator against overexcitation and will prevent it from generating too high currents in case of heavy inductive loads.

Features include
•    Protection of generators
•    Single phase measurement
•    Timer controlled tripping
•    LED indication of fault/activated relay
•    35 mm DIN rail or base mounting 

The RMQ-121D will thus protect the generator against damages caused by excessive heating of its windings, at the same time preventing transfer of reactive load to a faulty generator.
