Description

The 6RJ21 is a high burden self reset tripping relay suitable for applicationin high security circuit breaker tripping circuits & in particular where theinitiating contact may be remote from the relay. The high burden mayalso allow the satisfactory operation of external series elements.

The 6RJ21 has a high burden to provide immunity to capacitancedischarge currents. Power to the coil is economized to a low figure toprovide thermal protection.

High burden tripping relays are designed to withstand the 10uF capacitordischarge test such that the relay will not operate when a 10uF capacitorcharged to 120% of nominal operating voltage is applied across the coilof the relay.

The contacts & trip flag indication operate on application of a controlvoltage. Contacts are reset upon removal of the control voltage. The flagis reset using the front panel push button provided the contacts are inthe reset position.
