The RESYS M40 differential relay is combined with a triggered cut-off device (automatic power cut-off), to meet the following functions:
It also ensures the preventive monitoring of electrical installations with its pre-alarm function (configurable) or when used in signalling relays.
Automatic reclosing in case of unwanted tripping
The RESYS M40R differential relay is combined with a cut-off device equipped with a motorised control (automatic cut-off and restoration of power), ensuring the functions of:
detecting earth leakages and power outages. The relay re-engages the system up to six consecutive times after different time intervals. If the fault is still present after the sequence of six re-engage attempts, the relay enters an alarm state and manual intervention is required.
The RESYS P40 differential relay is combined with a triggered cut-off device (automatic power cut-off), to meet the following functions:
It also ensures the preventive monitoring of electrical installations with its pre-alarm function (configurable) or when used in signalling relays.
