ASJ earth leakage relay for residual current devices

Description: ASJ series earth leakage relays 1 Function 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 supply breaking. 2 Advantages Fully configurable • 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 configurable by the user. • Selection of toroid ratio. Tripping accuracy by TRMS measurement Improves immunity to nuisance tripping. Instantaneous display of permanent leakage currents The LED bargraph provides a real-time display of fluctuations in leakage currents.
