Amprobe ALC-110 Leakage Current Clamp

  • Measure:
      • Earth and differential leakage currents
      • Leakage currents through the earth (PE) conductor
      • Appliance current consumption without interruptions to the circuit
  • Trace the source of earth leakage currents
  • Identify intermittent GFCI trips without switching equipment off
  • Check a system for an electrical break of insulation where current is flowing to the ground
  • For use where industrial leakage current testing is required

Prevent unplanned downtime by detecting leakage currents with the ALC-110 Leakage Current Clamp. Rated CAT III 600 V to ensure electrical safety, the ALC-110 is designed to resist external magnetic fields for highly accurate readings. Features TRMS, a mechanical jaw lock, max readings and hold functions, highest resolution of 0.001 mA (measure up to 60 A), broad frequency range (15 Hz to 1 kHz), selectable filters (low pass, appliance, no filter), selectable limits (0.25 mA, 0.5 mA, 3.5 mA, 10 mA, 12 mA) and a battery-saving design.
