Geya 320A Molded Case DC Circuit Breaker GRM3-350HU by Lumett

The Geya 320A Molded Case DC Circuit Breaker GRM3-350HU is a heavy-duty DC molded case circuit breaker (MCCB) designed for compatible high-current direct-current electrical systems. It provides reliable circuit protection and isolation for appropriately engineered DC installations.

With a 320A rated current, the breaker is suitable for properly sized high-current applications where protection against abnormal current conditions is required. It can be incorporated into compatible solar PV systems, battery energy-storage systems, DC distribution panels, industrial DC equipment, telecommunications power systems, and renewable-energy installations.

The breaker helps protect suitable circuits against overload and short-circuit conditions when correctly selected and coordinated with other protective devices. Proper sizing and installation are essential to ensure that the breaker is compatible with the system voltage, connected load, conductor capacity, and available fault current.
