The Geya 320A Molded Case DC Circuit Breaker GRM3-350HU is a robust DC molded case circuit breaker (MCCB) designed for compatible high-current direct-current electrical systems. It provides circuit protection and electrical isolation for appropriately engineered installations.
With a 320A rated current, it is suitable for properly sized high-current applications where dependable DC protection is required. The breaker can be incorporated into compatible solar PV systems, battery energy-storage installations, DC distribution panels, industrial DC equipment, telecommunications power systems, and renewable-energy projects.
The device helps protect compatible circuits against abnormal current conditions such as overloads and short circuits when correctly selected and coordinated with the complete electrical protection system. Its molded-case construction makes it appropriate for applications requiring a more substantial protection device than a miniature DC circuit breaker.
Before installation, verify the system’s DC voltage, operating current, prospective fault current, conductor size, protection coordination, and installation conditions. Professional installation is recommended.
