Programmable short-circuit and earth fault indicator – Cabletroll 2320_2330


SKU: Cabletroll 2320_2330
Category:

Code: Cabletroll 2320/2330

 The CableTroll 2320/2330 indicators are fault current detectors for the underground medium voltage distribution networks (6-36kV). These indicators are used to detect short-circuit and earth faults and can be installed on most types of cable terminations.

These units will give separate indication for short-circuit and earth faults, locally by flashing diodes and remotely through separate relay contacts or additional ComTroll communication modules.

Fault detection

Earth fault:
– fix levels: 40, 60, 75, 80, 100, 150 şi 210 A (short bandwidth) and 45, 60, 75, 80, 100 şi 230 A (long bandwidth)
– continuous adjustable level: 5 ÷ 220 A (short bandwidth) and 5 ÷ 240 A (long bandwidth)
Short circuit fault: adjustable between 350 ÷ 1200 A (for 2320 type) and 250 ÷ 1000 A (at 2330 type)
Adjustable signaling delay period, independent for short-circuit and earth faults

Signaling reset

Automatic, by return of voltage
Timer: 2; 6; 8; 12; 16 or 24 hours
Manual, with reset button
Remote, closed contact
