Bussmann BKMDA Series Electronic Time-Delay Ferrule Fuse

Bussmann BKMDA Series Electronic Time-Delay Ferrule Fuse

The Bussmann BKMDA series from Eaton is an electronic time-delay ferrule fuse built with a ceramic tube body and nickel-plated brass endcaps for durable, consistent performance in electronic circuit protection. Measuring .25 IN in diameter and 1.25 IN in length, this ferrule end x ferrule end fuse is designed for electronic circuits and is available in amp ratings from 0.75A to 30A across the BKMDA family. Its time-delay characteristic lets it ride through momentary current surges while still reacting to sustained overcurrent conditions to protect connected equipment.

Key Features
