Strong Points
Function
The RESYS N40 ground leakage monitoring relay, used with a remote trip device (shunt trip or breaker), provide protection against indirect contact by detecting low-level ground leakage current and initiating a trip when the set threshold is exceeded.
The RESYS N40 supports preventative monitoring of electrical installations thanks to an adjustable pre-alarm (warning) output for early detection or can be used as a signaling relay.

Advantages
Fully configurable
• 2 relays with configurable function (alarm or pre-alarm at 50% IΔn).
• Adjustment of IΔn pickup current from 0.03 to 30 A.
• Time delay 0 to 10 s.
• Positive or negative security configurable by the user.
• Selection of CT ratio.
• Built-in NFC allows user to access and change settings via Smartphone/Device with installed app
Highly accurate
True RMS measurement ensures accurate trip response and minimizes nuisance tripping.
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
Enhanced electronics provide improved immunity to electromagnetic interference (EMC) for reliable operation.
