The RESYS M40 differential relay is combined with a triggered cut-off device (automatic power cut-off), to meet the following functions:
- Protect against indirect contact.
- Limit earth leakage currents.
It also ensures the preventive monitoring of electrical installations with its pre-alarm function (configurable) or when used in signalling relays.
