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

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

With a 320A rated current, this breaker is suitable for high-current installations where the protection device is correctly matched to the electrical load and system requirements. It can be used in compatible solar photovoltaic systems, battery energy-storage systems, DC distribution equipment, industrial DC installations, telecommunications power systems, and renewable-energy projects.

The breaker is intended to help protect compatible circuits from abnormal current conditions, including overloads and short circuits. For effective protection, it must be correctly coordinated with the cables, connected equipment, and other protective devices in the system.

Before installation, verify the required DC voltage, operating current, prospective fault current, conductor capacity, protection coordination, and environmental conditions. Installation should be performed by a qualified electrical professional.
