The 6RJ15 is a low burden hand & electrical reset high speed tripping relay suitable for applications where immunity to capacitance discharge & high minimum operation currents is not required.
The high speed relay coil is automatically protected from thermal damage by a series cutthroat contact once the relay contacts have picked up & latched.
The contacts can be reset using the front panel reset push button or via the electrical reset input.
The electrical reset coil is automatically protected from thermal damage by a series cutthroat contact once the relay contacts have been reset.
The trip flag can only be reset via the independent front panel reset push button after the contacts have been reset.
This feature allows the flag indication to be maintained as a record of trip operation even if the contacts have been electrically reset by remote control or by an auto reclose scheme.
The 6RJ13 version may be specified where the contacts & flag are reset simultaneously.
