Main disconnecting point (HRM)

Main Disconnect Device (HRM) is a device that serves to quickly disconnect electrical current from the distribution system. The main task of HRM is to ensure safe maintenance, repairs, or replacement of electrical equipment. This device is a key component of network protection, especially in solar panel systems, where it disconnects the production part of the source from the distribution system in the event of a fault or issues that could threaten network stability.

HRM is essential for the safe and reliable operation of electrical systems, particularly when renewable energy sources such as solar panels are used.
