RESYS M40 earth leakage relays, when used with a remote trip breaking device for automatic power interruption, deliver reliable protection functions for low-voltage electrical installations. They ensure protection against indirect contact and help limit earth leakage currents to maintain system safety and stability. In addition, these relays provide preventive monitoring of electrical installations through a configurable pre-alarm function and can also be used as signalling relays to enhance operational awareness and fault detection.
