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 leakage currents. They also preventively monitor electrical installations via their (configurable) pre-alarm function or when used as signalling relays.
• 2 relays with configurable function (alarm or pre-alarm at 50% I∆n) • Adjustment of I∆n from 0.03 to 30 A. • Time delay 0 to 10 s. • Positive or negative security configurable by the user. • Selection of toroid ratio.
Improves immunity to nuisance tripping.
The LED bargraph provides a real-time display of fluctuations in leakage currents.
44 mm in width, the unit allows easy integration 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.
The device has new electronics which improve electromagnetic compatibility.
