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 installations. It provides a robust means of circuit protection and isolation for appropriately engineered DC systems.

With a 320A rated current, this breaker is suitable for properly sized high-current applications where reliable DC circuit protection is required. Potential applications include solar PV systems, battery energy-storage systems, DC distribution panels, industrial DC equipment, telecommunications power systems, and renewable-energy installations, subject to system compatibility.

The breaker is designed to help protect compatible circuits against abnormal current conditions such as overloads and short circuits. For effective protection, it should be correctly coordinated with the cable size, connected equipment, upstream and downstream protection, and the overall system design.
