The Metrel S2051 Current Clamps are compatible with Metrel’s MI 2492, MI 2392, MI 2592 and MI 2792 Power Quality Analysers and can be used to measure the variable currents of small- and medium-power power plants.

These instruments have a 52mm jaw opening and feature four ranges: 0.5A, 5A, 100A and 1000A; the attached Metrel power quality analyser will select the appropriate range automatically. The Metrel S2051 Current Clamps are compliant with CAT III 600V safety requirements as well as EN/IEC 61010-1; EN/IEC 61010-2-32 and EN/IEC 61326-1 standards.

The Metrel S2051 Current Clamps feature an electronic module which facilitates a connection to compatible MI Power Quality Analysers. Furthermore, these instruments draw their power from the attached power quality analyser removing the need for a separate power source.

The Metrel S2051 Current Clamps are simple-to-use instruments designed for measuring variable currents when used with Metrel’s MI Power Quality Analysers.
