BK/MDL-1-1/2-R Description

Short technical summary and product information.

The Eaton BK/MDL-1-1/2-R is a 1.5A 250VAC slow blow glass cartridge fuse designed for overcurrent protection in a wide range of electronic and electrical applications. The fuse uses a glass tube construction with a 6.35mm x 31.75mm (1/4" x 1-1/4") form factor, fitting standard 3AB 3AG fuse holders.

 

With a slow blow (time-delay) response characteristic, this fuse tolerates temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive loads or motor starting. The rated breaking capacity is 100A at 250VAC, providing reliable fault interruption.

 

The fuse is approved by UL CSA and CE agencies, confirming compliance with international safety standards. It requires a holder for installation and is available in the standard 3AB 3AG package.
