Earth-leakage monitoring relay

Earth Leakage Relays TemProtect Earth Leakage Relays are used to monitor earth fault current with a view to protect electrical equipment and personnel against the dangers of such faults. Owing to the wide range of applications for the use of earth leakage protection, TemProtect has been designed to be as flexible as possible. The range includes relays suitable for installations with DIN rail, Panel or Base Mounting. All relays are suitable for use on a.c. systems and will be unaffected by d.c. components which may be present. A range of combined relay and toroidal current transformer is also readily available. The relays filter circuit inputs to safeguard against external disturbances in the system and offer the additional advantage of integral Test and Reset buttons, as well as integral Indication of Power and Trip. All the Earth Leakage Relays which have separate toroidal transformers constantly monitor the connection to the toroid and will trip should an open circuit occur. They also offer the choice of automatic, manual or remote resetting after a fault has occurred. All the relays comply to international standards including IEC 255.
