Bussmann GMT Series Fast-Acting Telecommunication Fuse

Bussmann GMT Series Fast-Acting Telecommunication Fuse

The Bussmann GMT Series is a line of fast-acting, non-indicating telecommunication fuses from Eaton Bussmann, engineered to protect low-voltage telecom, data, and electronic control circuits from damaging overcurrent conditions. This family is available in amperage ratings from 1/2 Amp to 15 Amp, letting you select the precise level of overcurrent protection your circuit requires, and every option in the series is rated 125 Vac and 60 Vdc for use in both AC and DC low-voltage telecom applications. Each fuse in the GMT Series uses a color-coding system that allows technicians to quickly identify its amperage rating during installation, troubleshooting, or replacement. Tin-plated beryllium copper terminals provide reliable, low-resistance contact in standard GMT fuse holders and blocks, while the fast-acting element responds quickly to fault conditions to help protect sensitive downstream components from damage. This GMT-series family is a direct, code-appropriate option wherever a 125 Vac/60 Vdc GMT fuse is specified, simply select the amperage rating that matches your application.

Key Features
