Cooper Bussmann BK/MDL-5 Time Delay Glass Fuse is a 5 A, 250 V small-dimension slow-blow fuse designed to tolerate brief inrush currents while protecting circuits from overloads. The device is a 1/4 in x 1-1/4 in (6 x 32 mm) glass tube with end caps, identified as BK/MDL-5-R and part of the MDL series. It carries an interrupting rating of up to 200 A at 250 VAC (and 10 kA at 125 VAC), making it suitable for power supplies, electronic controls, and equipment prone to startup surges. This MDL-5 fuse is commonly used in applications requiring reliable surge protection without excessive nuisance blows.
