Insulation monitoring device F4106

Also this device can be called: F-4106, F 4106, F41-06, F41 06.


F4106 insulation monitoring device is designed to measure the insulation resistance and alarm when it falls below a specified level (setpoint) in AC under voltage of 220 V or 380 V, 50 Hz, 60 Hz or 400 Hz.


Applications: mobile and stationary power plant with isolated neutral.


Devices F4106 consist of two units: the indicating device PU-F4106 and the relay device RU-F4106.
