Kyoritsu KEW 2431 AC Leakage Clamp Meter

Overview

The Kyoritsu KEW 2431 is a dedicated AC leakage clamp meter designed to measure the very small leakage (earth) currents that flow when insulation begins to break down. Clamping around a conductor or an entire circuit, it reveals leakage that ordinary clamp meters cannot resolve, making it an essential tool for finding wire faults, tracking down insulation breakdown and carrying out preventive maintenance on electrical installations.

The KEW 2431 offers three AC current ranges — 20 mA, 200 mA and 200 A — with a fine resolution of 0.01 mA, so it can both detect tiny leakage currents and measure normal load current with the same instrument. A frequency-selector switch lets the user filter out harmonics so that only the fundamental leakage current is measured, giving cleaner, more meaningful results, and a rotary switch allows easy one-finger power-on and range selection.

Key Features

• Dedicated AC leakage clamp meter for earth-leakage (Io) current.
• Three ranges: 20 mA / 200 mA / 200 A with 0.01 mA resolution.
• Detects tiny leakage currents and measures load current.
• Frequency-selector switch eliminates the effect of harmonics.
• Rotary switch for easy one-finger power-on and range selection.
• Ideal for finding wire faults and insulation breakdown.

Applications

• Measuring earth-leakage current in electrical installations.
• Locating insulation breakdown and wire faults.
• Preventive maintenance and periodic inspection.
• Troubleshooting nuisance RCD/ELCB tripping.
