Description

Engineered for reliable protection in electronic circuits, the Eaton Bussmann series time-delay fuse provides a robust solution for applications requiring both performance and safety. This fuse is rated for 32 Vac and 32 Vdc, with an amperage rating of 1/ 2A, ensuring it meets the demands of rigorous electrical systems. Designed with a glass tube and nickel-plated brass endcaps, it not only offers durability but is also lightweight and compact, measuring just 1.25 inches in length and 0.25 inches in diameter. The response time of this time-delay fuse is tailored for modern electronics, allowing a maximum of 60 minutes at 135% and providing ample protection against surges with a minimum response time of 5 seconds at 200%. Furthermore, its construction complies with UL, CSA, and CE certifications, assuring users of its reliability and performance standards. With features such as optional axial leads and board washable designs, this fuse is versatile for various configurations, making it an essential component in power distribution and protection setups.

Features

The Bussmann MDL-1/2-R features a dual-element, time-delay (slow-blow) design engineered to withstand temporary inrush currents and minor power spikes typical in small motors, transformers, and inductive loads. This prevents frustrating "nuisance tripping" during equipment startup while still providing critical overcurrent protection if a sustained overload or short circuit occurs.
This fuse is precisely rated for a 0.5 Amp current capacity at up to 250 Volts AC, making it an exact OEM replacement specification for low-amperage electronic circuits, control panels, and delicate appliances. Utilizing the correct 1/2A threshold ensures that your downstream components are shielded from dangerous electrical overloads without risking fires or board-level damage.
this is a standard industry-size 1/4-inch by 1-1/4-inch (6.3mm x 32mm) cartridge fuse designed to fit seamlessly into standard panel-mount fuse holders, inline blocks, and printed circuit board clips. The precise physical tolerances ensure a tight, low-resistance connection, eliminating the risk of voltage drops or arcing often caused by poorly manufactured aftermarket alternatives.
Featuring a high-clarity glass body with nickel-plated brass endcaps, this fuse allows for immediate visual inspection so you can confirm a blown filament at a glance. The rugged glass construction provides excellent thermal isolation and contains the electrical arc safely within the tube during a failure event, keeping your surrounding electronics pristine.
