Description
The 6RJ22 is a high burden self reset high speed tripping relay suitable for application in high security circuit breaker tripping circuits & where the initiating contact may be remote from the relay. The high burden may also allow the satisfactory operation of external series elements.
High burden tripping relays are designed to withstand the 10uF capacitor discharge test such that the relay will not operate when a 10uF capacitor charged to 120% of nominal operating voltage is applied across the coil of the relay.
The high speed relay coil is automatically economized by an integrated economizing circuit once the relay has picked up.
A delay release element provides an approximate 2 sec contact reset delay upon removal of the relay operate voltage.
The contacts & trip flag indication operate on application of a control voltage. Contacts are reset after removal of the relay operate voltage and an approximate 2 sec delay.
The flag is reset using the front panel push button provided the contacts are in the reset position.
