Bussmann MDQ-1 Series 250V Small-Dimension Time-Delay Fuse

Bussmann MDQ-1 Series 250V Small-Dimension Time-Delay Fuse

The Bussmann MDQ-1 Series 250V Small-Dimension Time-Delay Fuse is an Eaton Bussmann engineered overcurrent protection device built for circuits that demand dependable time-delay performance. Rated at 250V, this small-dimension fuse is designed to protect equipment and wiring from sustained overloads and short-circuit conditions while allowing brief, harmless current surges to pass without nuisance opening. Its compact, small-dimension form factor makes it well suited for space-constrained fuse blocks, control panels, and equipment where a standard-size fuse will not fit. As part of the Eaton Bussmann portfolio, the MDQ-1 is manufactured to consistent quality standards for dependable field performance, and it serves as a direct replacement in applications originally specified for a Bussmann MDQ series time-delay fuse.

Key Features

• Voltage Rating: 250V rating supports use in standard low-voltage branch circuits and equipment protection applications.
• Time-Delay Operation: Time-delay fuse element accommodates brief current surges, such as motor start-up or transformer inrush, without nuisance opening.
