Electromagnetic Disc Relay:

Torque is produced in these relays when one alternating flux reacts with the current induced in the rotor by another alternating flux displaced in time and space but having the same frequency. Induction relays are widely used for protective relaying involving a.c. quantities. High, low and adjustable speeds are possible, and various shapes of time/ operating quantity curves can be obtained.
