Bussmann GMD-1-R Time-Delay Fuse 250 Vac, 1A, Electronic, 0.625 Inch Length, 0.25 Inch Width

Description

Features

• The Bussmann GMD-1-R is a standard 5 x 20mm glass tube fuse, the most widely used metric dimension for small-scale electronic protection. The "R" suffix indicates full RoHS compliance, ensuring the component meets lead-free environmental standards for modern Canadian manufacturing and repair.
• This is a Time-Delay (Slo-Blo) fuse, engineered to withstand temporary current surges that would cause a standard fuse to "nuisance trip." It is specifically designed for circuits with inductive loads-such as small motors or power supplies with large filter capacitors-allowing for momentary inrush while still providing reliable protection against sustained overloads.
• Rated for 1 Amp at 250V AC, the GMD-1-R is ideal for protecting the primary side of small transformers and delicate electronic controllers. Its time-lag profile is calibrated to provide a specific window of "surge tolerance," ensuring your equipment powers up successfully without compromising the safety of the internal circuitry.
• The clear glass body allows for instant visual troubleshooting without the need for a multimeter. You can easily verify the integrity of the internal filament or check for the dark "burn" marks that indicate a high-energy short circuit, significantly reducing diagnostic time for Canadian maintenance technicians and DIYers.
• As a glass-bodied supplemental fuse, it features a low breaking capacity, typically rated to safely interrupt 35A at 250V AC or 10,000A at 125V AC. It is intended for use inside equipment to protect specific internal components; it should not be used as the primary branch circuit protection for a building's electrical system.
