Earth Leakage Relays
The earth leakage relays represent the solution against accidental contacts in industrial applications. The adjustment of the devices both in terms of the operating threshold and time permits upstream and downstream selectivity with indubitable advantages in relation to operation continuity. These relays are available in the following types: with 1-operation threshold, with 2-operation threshold, remote control reset device, toroidal current transformers, and as external multiplier. Features include: modular, flush and internal panel mount version, with or without flag indicator, configurable pre-alarm indication and fail safe operation, version with automatic toroid connection control, choice of supply voltage ranges, adjustable fault current and adjustment and choice of tripping range for both fault current and delay time. These relays are offered by Lovato Electric, one of the first companies in Italy to obtain ISO 9001 certification in 1992.
