Insulation monitors are used for protection of persons and against fire in non-grounded systems (IT systems). The insulation resistance of the system being monitored is measured against ground.

These types of measurements are specified according to DIN/VDE 0100-410 – Erection of power installations up to 1000 V – Protection against electric shock.

Benefits

• The insulation monitoring for AC voltage systems of up to 500 V AC and 1000 Hz enables application in 400 V three-phase systems
• Easy operation with potentiometers as the set limit value of the insulation resistance is always visible
• Simple and cost-efficient solution for remote signaling and signaling due to option for connecting an external LED and/or external testing and canceling pushbutton
• Simplified planning and logistics as no auxiliary voltage is required for the insulation monitoring of direct voltage systems up to 280VDC.
