megger dcm305e clamp meter

The Megger DCM305E Earth Leakage Clamp Meter is a precision instrument designed to pinpoint and measure earth leakage currents in electrical circuits. This tool is particularly useful in scenarios where Residual Current Devices (RCDs) trip unexpectedly, allowing technicians to quickly ascertain whether the issue is due to excessive leakage current or a malfunctioning RCD.

High-Resolution Measurement: The DCM305E features impressive sensitivity with a resolution as low as 0.001 mA in the 6 mA range, making it ideal for detecting very small earth leakages that other instruments might miss. This high resolution extends across its broader range of up to 100 A for standard AC current measurements, ensuring versatility in both minor and significant electrical assessments.

Advanced Design and Functionality: Equipped with a 40 mm jaw, the DCM305E facilitates easy and safe measurements on both insulated and non-insulated conductors. This feature is especially beneficial in environments with space constraints or where safety is a concern. The inclusion of a low pass filter aids in stabilizing readings by reducing the effects of harmonics and electrical noise, enhancing the reliability of the measurements.
