Function
RESYS M40 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
IEC 60755

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 modular design
At 44 mm wide, the device is easily integrated into dedicated enclosures.
The adjustment buttons are protected by a sealable cover, while the display of available alarms is displayed directly on the front face of the device.
Improved immunity to EMC interferences
The device has new electronics which improve electromagnetic compatibility.
