The ELD V3 relay utilises a microprocessor design, providing a definite time operating characteristic with adjustable trip sensitivity and time delay.
The relay latches when tripped and provides normally open and change-over relay contacts. The relay supports an external reset switch, and a 4-20mA interface allows external monitoring.
The ELD V3 Earth Leakage Relay is housed in a stainless-steel case and can be either ‘DIN Rail’ or ‘Panel’ mounted through a 69 x 39mm IP56 ingress protected cut out. An attachment to prevent unauthorised adjustment of the trip settings is available separately.
The Ampcontrol ELD V3 Earth Leakage Relay has been designed and approved for use on earth fault-limited systems, namely coal mining applications, providing earth leakage protection (earth fault protection) as per AS/NZS 2081:2011. It is also suitable for other applications where equipment or system earth leakage protection is required.
