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 circuit protection device designed for compatible high-current direct-current electrical systems. Its molded-case construction provides a robust solution for applications requiring circuit protection and controlled isolation.

With a 320A rated current, the breaker is suitable for appropriately designed high-current DC applications where protection against abnormal current conditions such as overloads and short circuits is required. It can be considered for compatible solar photovoltaic systems, battery energy-storage systems, DC distribution equipment, telecommunications power systems, and industrial DC installations, subject to the manufacturer’s specifications and correct system design.

The GRM3-350HU is intended for professional electrical installations. Proper selection should take into account the system’s DC voltage, operating current, prospective short-circuit current, cable capacity, protection coordination, and installation conditions. A qualified electrical professional should handle installation and commissioning.
