Earth Leakage Protective Relays BRR, RRD and EL series
Earth leakage protective relays
Description In the earth leakage relay the breaking mechanism is omitted from the ELCB, and the ZCT and earth leakage tripping device are integrated into a common body. These relays are available in both instantaneous and time-delay versions. Generally these relays are used in conjunction with MCCB’s, ACB’s and motor starters.
