ASJ series earth leakage relays associated with a remote trip breaking device(automatic power breaking),provide the following functions:
protection against indirect contact.
limitation of leakage currents.
Type Aearth leakage detection and power supplybreaking.
2 relays with configurable function(alarm or pre-alarm at 50% IΔn).
Adjustment of IΔn from 0.03 to 30 A.
Time delay 0 to 10 s.
Positive or negative security configurableby the user.
Selection of toroid ratio.
Tripping accuracy by TRMS measurement:
Improves immunity to nuisance tripping.
Instantaneous display of permanentleakage currents:
The LED bargraph provides a real-time displayof fluctuations in leakage currents.
