1.1 Overview

Telect’s High-Power GMT Series Fuse Panels provide protected secondary -48 VDC to telecommunications equipment at the bay level (-48 VDC, nominal). Fuse panels are available with GMT fuses in single-circuit (10, 20, and 30) or dual-circuit (10/10, 15/15, and 20/20) configurations.

Shown on the right are the front and rear images of a Dual-Circuit High-Power 10/10 GMT Fuse Panel and a front corner view of a 10/10 GMT TFA Fuse Panel.

Standard features include:

• Single- or dual-circuit, 100A input bus(es), -48 VDC
