Bussmann MDQ Series Small-Dimension Time-Delay Fuse, 250V

Bussmann MDQ Series Small-Dimension Time-Delay Fuse, 250V

The Bussmann MDQ Series time-delay fuse from the Eaton Bussmann series is rated 250V for dependable overcurrent protection on electrical circuits, and this family is available in amperage ratings from 0.375 Amp to 2 Amp to match a range of low-current protection needs. Designated in manufacturer records as a small-dimension, time-delay (TD) fuse, it is engineered to ride through momentary inrush and start-up current spikes that are common on motor loads, transformers, and other equipment with high initial current draw, while still opening promptly on sustained overloads or short-circuit conditions. Every fuse in this family carries a 100 kiloamp interrupt rating and terminates in Ferrule end connections, giving contractors a consistent platform across the available amperage options. As part of the trusted Eaton Bussmann series, this fuse gives electrical contractors, panel builders, and facility maintenance teams a compact, code-familiar option for standardizing overcurrent protection across a facility. Its small-dimension body is sized to install in standard small-dimension fuse holders, blocks, and disconnects without modification, simplifying stocking and replacement for maintenance crews. Fuses in this small-dimension form factor are commonly stocked alongside other Bussmann time-delay fuses, helping simplify inventory for facilities that rely on a single time-delay fuse platform across multiple circuits and amperage requirements.
