Megger DCM305E Earth Leakage Clamp Meter
The Megger DCM305E Earth Leakage Clamp Meter delivers high-precision AC current measurement, ranging from just 0.001 mA up to 100 A. Designed with both flexibility and safety in mind, it supports work on uninsulated conductors while ensuring TRMS accuracy across all six current ranges. With the added benefit of a robust 40 mm jaw, it simplifies current monitoring on busbars and multiple conductors.
Optimised for Low Leakage Measurement
Featuring a selectable low-pass filter at 50/60Hz, the Megger DCM305E ensures stable and reliable readings even in noisy environments. This is especially useful for circuits affected by harmonic distortion, allowing you to confidently analyse earth leakage and load current without interference. The device includes a compare mode, enabling the user to check current levels against three preset thresholds (0.25 mA, 0.5 mA, and 3.5 mA), accompanied by audible or visual alerts.
Smart Functions for Everyday Use
To improve workflow and usability, the Megger DCM305E includes several hold options. These include auto hold, data hold, and peak hold. It also features automatic backlighting for use in poor lighting conditions. The clamp is equipped with auto-ranging for ease of use. A self-check function runs automatically at start-up. The 20-minute auto power-off feature helps conserve battery life. Its durable design includes a protective jaw. A zipped pouch is also supplied, making it safe to transport and easy to store in any toolkit.
Whether you’re assessing leakage during system maintenance or monitoring electrical safety, the Megger DCM305E provides accuracy, reliability, and ease of use. With CAT III 300 V safety ratings and high sensitivity, it’s ideal for engineers working in industrial, commercial, or facilities management sectors.
