Application

The 6RJ34 is a bi-stable control relay designed to switch protection and auto reclosing IN and OUT of service from a remote point via pilot wires.

Application of a control signal to the operate coil inputs will cause the relay to pick upchanging the state of the contacts and flag to the OUT condition.

Application of a control signal to the reset coil inputs will cause the relay to drop out revertingthe contacts and flag to the IN condition.

The operate and reset coils are automatically protected from thermal damage by a series cutthroat contacts once the relay contacts have changed state.

An electrical reset inhibit function is provided to isolate the reset circuit when a voltage isapplied to the operate coil. This avoids the possibility of the relay cycling between the IN andOUT state if the operate and reset coils are energized at the same time.

A feature of the design is that the 6RJ34 will neither operate nor reset if 110V AC 50Hz rmsis applied across either the operate or reset circuits in accordance with National GridCompany SPEC.NGTS 2.19.1999.

Up to 20 contacts may be specified in any combination with a maximum of 10 break.

Where only 10 contacts are required refer to the 6RJ34-10 Technical Bulletin.
