SPMR series residual current devices are electrical safety devices that protect people from electric shock and prevent fires. They work by detecting the difference between the current entering and leaving the circuit, disconnecting the power supply if an abnormality is detected.

Electric shock protection:
The main task of residual current devices is to protect people from electric shock, both in the case of direct contact (e.g., touching a live wire) and indirect contact (e.g., touching the housing of a damaged device).

Fire protection:
Residual current devices help prevent fires that can be caused by short circuits or damage to the electrical system by responding to leakage currents and cutting off the power supply.

Protection in various conditions:
They are used in domestic installations, in places with an increased risk of electric shock (e.g., bathrooms, kitchens),
as well as in industrial facilities, construction sites, and farms.
