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 design makes it suitable for installations requiring robust circuit protection and reliable electrical isolation.

With a 320A rated current, the breaker is intended for appropriately designed high-current DC applications. It can be incorporated into compatible solar PV systems, battery energy-storage systems, DC distribution panels, industrial power systems, telecommunications infrastructure, and other high-current DC installations.

The breaker helps provide protection against abnormal current conditions, including overload and short-circuit events, when correctly selected and coordinated with the rest of the electrical protection system.

Before installation, users should verify the required DC voltage rating, operating current, prospective fault current, conductor size, protection coordination, and environmental conditions. Installation and commissioning should be carried out by a qualified electrical professional.
