An Earth Fault relay that will monitor and detect when the measured current exceeds the set trip threshold and de-energise the output relay after a pre-determined delay based on the curve chosen, the level of current and Time multiplier setting.
Two levels of tripping thresholds are provided (both adjustable) allowing the user to set a “Low-set” and “High-set” trip point. The operation of the tripping curve is only applicable when the Low-set trip point is exceeded. If the measured current exceeds the High-set trip point, the relay de-energises straight away.
An auxiliary supply (required to power the unit) must be present for the product to function.
