OverviewOperation principlesTypes according to constructionRelays by functionsPower source

Electromechanical protective relays operate by either magnetic attraction, or magnetic induction. Unlike switching type electromechanical relays with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics. Protection relays may use arrays of induction disks, shaded-pole, magnets, operating and restraint coils, solenoid-type operators, telephone-relay contacts
