Applications
Auxiliary Relay and Trip Relay
1. The design, durability and quality of these relays guarantee their application in high responsibility controls such as power stations, substations, and process industries.
2. Applications are for general contact multiplication, interlocking, and customising of protection schemes.
3. To use in relay coordination and to provide control commands or signal commands to other devices in use
4. To provide durability and quality of response

Auxiliary relay is available in 3 NO contacts and 2 CO contacts with self reset contacts type with or without flag.
Trip relay low burden is available in 3 NO and 3 NC contacts. Trip relay high burden is available in 3 NO and 2 NC contacts with hand reset contacts type. Auxiliary Relay and Trip Relay is used in high speed operation which suits the requirements like transmission and industrial applications. Auxiliary Relay Operation When auxiliary voltage is supplied to the relay coil terminals, the auxiliary relay operates within the expected time and the Normal Open (NO) contacts and Change Over (CO) contacts will change their states. During the contacts change, the flag operates and
indicates the relay has tripped. Auxiliary relay resets when the coil terminal voltage is disconnected.You can manually reset the auxiliary relay flag indication by pushing the flag plunger inside.

Trip Relay Operation :-
1. When auxiliary voltage is supplied to the relay coil terminals, the trip relay operates within the expected time
and the contacts will change from Normal Open (NO) to Normal Close (NC) state and vice-versa. During the contacts change, the flag operates and indicates the relay is tripped and the hand reset plunger operates to keep the contacts in latched mode
2. Before resetting the trip relay, you should ensure that the auxiliary voltage is disconnected from the coil terminals or the trip command from any numerical relay should be disconnected
3. For reset of trip relay manually, pull the hand reset plunger. The flag indication can be reset by pushing the flag plunger inside.
