Description of current clamps
The A 1588 multi range current clamps are designed for measuring alternating currents on low
and medium power installations: 50
mA ÷ 50 A.
They have electronic module, and can be connected only to Metrel PowerQ series of measuring
instruments:
Energy Master (MI 2883)
Master Q4 (MI 2885)
Power Master (MI 2892)
Clamps have three current ranges 0.5A, 5A and 50A, which are selected directly by the
connected instrument. Embedded electronic module is powered directly from the connected
instrument and does not need any additional power supply.
The current transducer is housed in a plastic case that maintains double insulation as defined in
Main parts of the current clamps are shown on figure bellow:
1. handles,
2. safety barrier,
3. conductor opening,
4. clamps jaw,
5. cable connection with
connector.
