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 MCCB designed for compatible high-current direct-current electrical systems. It provides a robust solution for circuit protection and electrical isolation in appropriately designed power installations.

With its 320A rated current, this breaker is suitable for high-current applications where dependable DC protection is required. It can be incorporated into compatible solar photovoltaic systems, battery energy-storage systems, DC distribution panels, industrial DC installations, telecommunications power systems, and renewable-energy projects.

The breaker helps protect compatible circuits against abnormal current conditions, including overloads and short circuits, when properly selected and coordinated with other protective devices. It can also provide a practical isolation point for suitable DC circuits during maintenance.

Before installation, the system should be assessed for DC voltage, operating current, prospective short-circuit current, conductor size, protection coordination, and environmental conditions. The breaker must be installed according to applicable electrical requirements by a qualified professional.
