GA Earth Leakage Relay

Pioneers of the harmonic suppression circuit characteristics, the GA Earth Leakage protection relay enables more sensitive earth leakage protection of high kilowatt motors started direct-on-line as well as variable speed drive applications without nuisance tripping.

Available in diverse configuration options, including Latched or Non-latching main trip contact, Fail-safe or Non Fail-safe options, as well as 110V-220V or 380V-525V A.C. auxiliary supply voltages.

The trip contact current rating is a sturdy 6A at 220V and 3A at 525V A.C. A latched ‘contactor trip’ change-over contact can only be reset by pressing the control panel mounted pushbutton.

Sensitivities range from 30mA to 1000mA with user selectable instantaneous or IDMT curve selection while using the same earth leakage core.
