Megger DCM300E-Earth Leakage Clamp Meter

The Megger DCM300E Earth Leakage Clamp Meter is a specialized tool designed for precision measurement of earth leakage currents, providing essential diagnostics in electrical installations and equipment. It is particularly engineered with a high sensitivity range, offering resolutions down to 0.01 mA, which is ideal for detecting very low earth leakage currents that could be causing protective devices like Residual Current Devices (RCD) or Ground Fault Circuit Interrupters (GFCI) to trip.

This clamp meter is fully compliant with EMC (Electromagnetic Compatibility) standards and meets the rigorous requirements of IEC61010-2-032, ensuring that it is safe and reliable for use in various electrical testing environments. Its capability to measure currents across a broad spectrum — with ranges of 30 mA, 300 mA, 30 A, and 300 A — makes the DCM300E highly versatile. Whether checking for leakage in circuits to troubleshoot nuisance trips of RCDs or GFCIs, or for general AC current measuring, this meter handles tasks with accuracy and ease.

The DCM300E features a 40 mm jaw size, which is optimally designed to clamp around cables and conductors in dense wiring environments comfortably. It combines both an analogue bar graph and a digital display, providing dual-mode visualization of measurements that enhance readability and user experience. The analogue bar graph is especially useful in observing fluctuations and trends in current flow, allowing for real-time monitoring and faster decision-making.
