- Description
Description
Characteristics :
- Assembly: OMEGA busbar – DIN EN 50022
- Dimensions: width 157.5 mm (9 17.5 step modules)
- Compliance with EN 61557-1; Part 8.
Application :
- Any industrial application in IT systems connected to 1-Ph and 3-Ph networks up to 500 V with neutral isolated from earth downstream of the isolation transformer.
This ground fault detection ISOLTEST industrial series has been developed for any industrial application for continuous monitoring of insulation earth resistance in systems connected to 1-Ph and 3-Ph grids up to 500 V with a neutral isolated from earth downstream of the isolation transformer.
When the insulation resistance drops below a specified value (expressed in kohm), the ISOLTEST industrial series of earth fault detectors cuts in, activating an audible signal and an optical indicator.
Calibration is carried out by a potentiometer on the front of the unit, allowing control from 5 kohm to 150 kohm; a green LED (NORMAL) indicates the insulation status, a red LED (ALARM) indicates the fault statu There are also two TEST and RESET buttons.
Remote optical and acoustic indicators can be connected to the rear unit along with the usual check buttons for testing and resetting.
