BK/GMC-3A Description

Short technical summary and product information.

The Eaton BK/GMC-3A is a 3A, 250VAC medium-blow glass cartridge fuse designed for overcurrent protection in a wide range of electronic and electrical applications. Housed in a standard 5x20mm package, this fuse requires a holder for installation, making it suitable for panel-mount or in-line fuse holders.

 

With a breaking capacity of 100A at rated voltage, the BK/GMC-3A provides reliable fault current interruption. Its medium-blow (time-delay) characteristic allows it to tolerate brief inrush currents without nuisance opening, ideal for circuits with capacitive or inductive loads.

 

The fuse carries approvals from UL, CSA, KC-MARK, and MITI, indicating compliance with international safety standards. The glass construction offers visual indication of fuse status. This part is commonly used in power supplies, lighting, and industrial control equipment.
