Bussmann MDL-1-R 1 Amp 250V Slow-Blow Glass Fuse

The Bussmann MDL-1-R is a 1 amp, 250 volt slow-blow (time-delay) glass fuse designed for circuit protection in electronic equipment and instrumentation. This small dimension fuse features a compact 5mm x 20mm (3AG) glass tube construction that provides reliable overcurrent protection while allowing visual inspection of the fuse element.

Key Features:

• 1 amp current rating with 250V AC/DC voltage capacity
• Slow-blow (time-delay) characteristic prevents nuisance opening from harmless current surges
• Standard 5mm x 20mm (3AG) glass tube dimensions for universal compatibility
• Glass body allows visual verification of fuse condition
• Nickel-plated brass end caps ensure reliable electrical contact
• Meets UL/CSA safety standards for component fuses

The MDL series is ideal for protecting sensitive electronic circuits, control panels, power supplies, and instrumentation where temporary inrush currents occur during startup. The time-delay characteristic provides protection against sustained overcurrent conditions while tolerating brief harmless surges, reducing unnecessary downtime and replacement costs.
