Strong Points
Function
RESYS P40 earth leakage relays associated with a remote trip breaking device (automatic power breaking), provide the following functions:
- protection against indirect contact,
- limitation of earth leakage currents.
They also preventively monitor electrical installations via their (configurable) pre-alarm function or when used as signalling relays.
Conformity to standards

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.
Compact flush-mounting case
Measuring 48 x 48 mm, it is particularly suitable for integration into low-height pull-out drawers.
Improved immunity to EMC interferences
The device has new electronics which improve electromagnetic compatibility.
