Insulation monitoring according to IEC/EN 61557-8 Detection of symmetric and asymmetric insulation faults Measuring circuits can be disconnected via control terminals, e.g.for mains couplings 1 changeover contact each for prewarning and alarm 3. output relay for signalling wire break and device faults Prewarning threshold setting range: 20 k&Omega, ... 2 M&Omega, Alarm threshold setting range: 1 k&Omega, ... 250 k&Omega, Energized or de-energized on trip can be selected for output relay Setting the maximum leakage capacitance to shorten the response time Simple, clearly arranged adjustment of the device with screwdriver LED chain to indicate the current insulation resistance Display of active measuring circuits Automatic and manual device self-test Alarm storage selectable External test and reset pushbutton can be connected Width: 90 mm''
