Megger DCM 300E - Earth Leakage Clamp Meter
The Megger DCM300E is a high-sensitivity clamp meter designed to measure earth leakage currents quickly and safely without disconnecting circuits. This compact instrument is widely used in industrial and commercial electrical systems for troubleshooting nuisance tripping of RCDs/ELCBs and detecting insulation leakage issues.
Features & Benefits
- Measures earth leakage currents from 30 mA to 300 A AC with high accuracy.
- High resolution up to 0.01 mA (10 B5A) for precise diagnostics.
- Clamp-on design allows non-intrusive, quick measurements on live systems.
- Dual display combining digital reading and analog bar graph for clear visualization.
- Data hold function and auto power-off for user convenience and battery saving.
- Compliant with IEC 61010-2-032 safety standards, ensuring safe operation.
Use Cases / Applications
- Detecting earth leakage to prevent equipment damage and enhance electrical safety.
- Troubleshooting nuisance trips in residual current devices (RCDs) and earth leakage circuit breakers (ELCBs).
- Conducting preventive maintenance and electrical safety diagnostics on commercial and industrial electrical installations.
