100A/60A Universal Voltage GMT Fuse Panels 
With Enhanced Power/Fuse & Bay Alarms

Power

  ::  HPGMTXX & GMTXX

1.1 Overview

Telect’s 60A and 100A GMT Panels are
compact 1RU EIA power panels enabling
+ 24 and -48 Vdc power protection for a
variety of wireline and wireless
telecommunications and data equipment.
Most GMT-Series panels fit either 19-in. or 23-in. 
racks. (See the comparison chart on page 2.) 
All panels are white except HPGMT10-BLK, 
which is black. 

The panel provides total front access to fuses and LED status. Below the bezel holding the status LEDs is a  
pull-out designation card holder. 

All terminals for inputs, outputs, ground, and alarms are on the same side — either all on the rear or all on the 
front. All terminals are covered by a single full-width transparent terminal cover:

•  Inputs are either dual-hole lugs for studs (100A panels) or bare conductors for barrel connectors (60A 

panels).

•  Ground terminals accept either single- or dual-hole lugs.

•  Output screw-post terminals accept either ring or forked lugs, as well as bare wire.

•  Power/fuse and bay alarms terminals, along with external bay alarm trigger terminals, are wirewrap pins.

GMT-Series panels differ in load rating (60A or 100A), capacity (10, 15, or 20 GMTs per side), single or dual feed, 
and total front access (GMT10FA) panels vs. panels with rear-side terminals. All panels are 1RU. 

The GMT fuse holders are mounted upside-down so that the GMT indicator flag flips downward when activated, 
making identification and detection easier, especially on tall racks. In addition, the GMT fuse holders are mounted 
separately — not as a fuse block — thereby making fuse- position management unnecessary when dealing with 
10A, 15A, and 20A GMT fuses. Holes for color-coded fuse designation pins are located below each fuse position. 

The panel also features separate power and fuse failure status LEDs and power alarm relay connections for each 
feed. Major and minor bay alarm LEDs and wirewrap terminals are controlled via an on-board relay triggered by 
an external switch closure. All on-board relay contacts are dry Form-C. All LEDs and alarm relays and contacts are 
located on an easily removable alarm card.
