SC and SC-1 current relays are suitable for any application where an instantaneous plunger relay of high accuracy is required. These relays are utilized for protective service, and for auxiliary service where some of their features are desired.
The Type SC line of relays are adjustable over a wide range of current. Each relay is provided with a mechanical operation indicator and a calibrated scale to indicate the pick-up setting.
The high drop-out to pick-up ratio (85-98%) of the Type SC relays make them particularly suitable for use as fault detectors to supervise main protective relays.
The Type SC-1 has a lower ration of drop-out to pick-up. This lower ratio makes possible a plunger pull characteristic which permits operation of a latching device.
These relays must not be used in critical applications where they may be pick-up for prolonged periods of time.
