Geya 100A Miniature DC Circuit Breaker GYM9-125DC-100 by Lumett

The Geya 100A Miniature DC Circuit Breaker GYM9-125DC-100 is a compact DC protection component designed to help protect compatible electrical circuits from overload and short-circuit conditions. It provides circuit protection and isolation for appropriately designed direct-current electrical systems.

This 100A DC MCB is suitable for applications where DC circuit protection is required, including compatible solar photovoltaic (PV) systems, battery storage installations, DC distribution boards, telecommunications equipment, and other DC electrical applications. Its compact format makes it practical for integration into suitable electrical panels.

The 100A rating should be matched carefully to the connected circuit and equipment. Before installation, users should confirm the system’s DC voltage, operating current, fault current, cable size, protection requirements, and the manufacturer’s specifications.

As part of a properly designed protection system, the breaker can help reduce the risk associated with excessive current caused by overloads or short circuits. It may also serve as a convenient means of isolating a compatible DC circuit during maintenance.
