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.
