Bussmann GMA-3-R Fast-Acting Fuse 3A 32Vdc Glass Tube 0.25 Inch x 0.197 Inch

Description

Features

• The Bussmann GMA-3-R is a standard 5 x 20mm glass tube fuse, the most common metric dimension for small-scale electronic protection globally. The "R" suffix indicates full RoHS compliance, ensuring the component meets lead-free environmental standards for modern Canadian electronics repair and manufacturing.
• This is a Fast-Acting fuse, designed to open almost instantly when an overcurrent is detected. This rapid response is critical for protecting sensitive electronic components-such as those found in power supplies, audio equipment, and instruments-that cannot withstand even brief surges without sustaining permanent damage.
• Rated for 3 Amps at 125V AC (also commonly used in 250V applications with a lower interrupting rating), the GMA-3-R is designed for medium-current electronic loads. Its fast-clearing curve is specifically calibrated to interrupt the circuit at the first sign of a fault, acting as a "safety valve" for your delicate hardware.
• The clear glass body allows for instant visual troubleshooting without the need for a multimeter. You can easily verify the integrity of the internal wire filament; a break or a dark "burn" mark inside the tube indicates a cleared fuse, allowing Canadian maintenance technicians and DIYers to diagnose power issues at a glance.
• As a glass-bodied supplemental fuse, it features a low breaking capacity, typically rated to safely interrupt 10,000A at 125V AC or 100A at 250V AC. It is intended for use inside a device to protect internal components; it should not be used as the primary branch circuit protection for a building's electrical system.
