Strong Points
Function
RESYS N40 earth leakage relays associated with a remote trip breaking device (automatic power breaking), provide the following functions:protection against indirect contact and 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
IEC 60947-2 Annex M
IEC 62020
IEC 61543 A1
UL 508
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.
- Built-in NFC allows user to access and change settings via Smartphone/Device with installed app.
High accuracy
TRMS measurement trigger accuracy which reduces false triggers.
Effective Visualization of Leakage Current
The application and the product’s front panel provide clear, real-time monitoring of leakage current. The LED bargraph instantly displays fluctuations, enabling precise tracking of current variations.
Improved immunity to EMC interference
The RESYS N40 has new electronics which improve electromagnetic compatibility.
