8 fuse module ensures short-circuit protection of power supply outputs of exchange and subscriber units of Armtel digital Intercom and PAGA communication systems, that can occur in both communication line and inside the communication system device. Module is installed in conjunction with switching equipment of communication systems in 19-inch racks or cabinets in hardware, control rooms or office premises.

Distribution of power supply voltage 48VDC to eight lines connected to the module through fuses;
Fault signal indication (any fuse blowing) byway of LED and closing relay contact. It can be used for failure signaling using external executive device (lamp, buzzer, etc.);
LED indication of fault at failure of any or all fuses;
Module is made as printed circuit board with DIN-rail 35/7.5 clamping elements. Wires of power and fault signal generation lines are connected through screw terminals.
