Description of THYTRONIC RMT/1 device - earth leakage protection relay (earth fault)

RMT/1 is an Earth Fault / Residual Current Relay (Earth Fault / Residual Current Relay) used in low voltage (LV) networks with TT or TNS earthing system. This device is designed to protect against leakage currents or earth faults and can operate instantaneously or with a set time delay.

The main features of the device

✅ A performance adjustment level

The relay has a leakage current setting threshold that can operate instantaneously or with a specified time delay.

✅ Can be used in TT and TNS networks

These two types of earth systems are used in electricity distribution networks and the device is compatible with both.

Due to its small size, the relay is easily installed in limited spaces such as MCC (Motor Control Center) panels and small enclosures.

✅ Suitable frame for flush mounting

The device is designed in such a way that it can be installed inside the panel with low depth and creates a regular appearance.

✅ It has a transparent cap that can be sealed

The front cover is transparent and can be sealed so that no one can change the settings of the device without permission.

This feature is very important for industrial panels.
