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

The Geya 100A Miniature DC Circuit Breaker GYM9-125DC-100 is a compact protection device designed for compatible direct-current (DC) electrical circuits. It helps provide protection against excessive current caused by overload and short-circuit conditions while also offering a practical means of circuit isolation.

This 100A DC MCB can be incorporated into appropriately designed solar PV systems, battery storage installations, DC distribution boards, telecommunications equipment, and other compatible DC applications. Its miniature format makes it convenient for installation within suitable electrical panels and protection enclosures.

The 100A rated current should be selected according to the actual requirements of the electrical circuit. System voltage, operating current, fault level, conductor size, installation conditions, and equipment compatibility should all be verified before installation.

For solar and renewable-energy installations, appropriate DC protection is important for helping protect wiring and connected equipment from abnormal current conditions. The breaker should form part of a properly designed electrical protection system and be installed by a qualified professional.
