    Leakage Current Alarm

    MPU-1 is dedicated measurement of leakage current in AC, low and medium voltage power network.  Working with dangerous voltage lines, one piece of equipment to improve safety is an instrument for continuous monitoring of leakage current. Designed to indicate networks safety condition for leakage current. The device enable you to set maximum safe level of flowing leakage current which will activate visual and audible alarms.

    Important features of MPU-1 Leakage Current Alarm Signaler:

    • Constant monitoring of current flowing on earthing
    • Measurement with the use of single clamp or two clamps simultaneously. In case of using two clamps, current value is summed up,  which allows for checking twin pylons (rotational), with independent clamp for each component pylon,
    • Work mode LED indicator,
    • Visual and sound alarm (speaker built in cover) in case of higher value of leakage current than define limit (factory default set to 1A),
    • Battery level monitoring,
    • No DC current measurement,
    • Measurement with flexible clamp (Rogowski coil) - Sonel F series,
    • Measurement in 50Hz or 60 Hz frequency low and medium voltage networks,
    • Auto ranging,
    • Ergonomic handling
    • MPU-1 for operation requires F1, F-2 or F-3 clamp (additional accessories)
