Megger DCM300E Clamp-on Current Leadage Tester

Description

The Megger DCM300E is a clamp-on current leakage tester designed primarily for detecting earth leakage currents in electrical installations. Its highly sensitive 30 mA range, with a resolution of 0.01 mA, allows it to detect even very small leakage currents. The device is also capable of measuring higher AC currents up to 300 A, making it a versatile tool for general current measurements.
