Megger DCM300E Earth Leakage Clamp Meter

Reliable Earth Leakage Testing for Electricians

The Megger DCM300E Earth Leakage Clamp Meter is designed for electricians and electrical maintenance technicians who need fast, non-invasive earth leakage testing. Ideal for fault finding and RCD troubleshooting, it measures leakage current without disconnecting wiring, helping to identify insulation faults quickly and safely.

 

Accurate Current Measurements

With four measurement ranges from 30 mA to 300 A AC, the DCM300E delivers high sensitivity with 0.01 mA resolution for leakage current testing, while also handling standard load current measurements. The digital display, analogue bar graph and Data Hold function make readings easy to capture, even in confined or poorly lit locations.

 

Built for Everyday Electrical Maintenance

Featuring a 40 mm jaw opening, automatic power-off and a rugged lightweight design, the DCM300E is ideal for routine electrical inspections. How does the DCM300E improve fault finding? It allows electricians to pinpoint earth leakage currents quickly without dismantling circuits, reducing downtime and simplifying electrical maintenance.
