Overview
Features
Specifications
Calibration
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.
Application
- 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 current
- Identify intermittent GFCI trips without switching equipment off
- Low influence of external magnetic fields
- True-rms measurements for accuracy when measuring complex, non-sinusoidal waveforms
- Mechanical jaw lock to assure accuracy of low current measurements 30 mm (1.2 in) jaw opening
- Highest resolution of 0.001 mA
- Measure up to 60 A
- Broad frequency range 15 Hz to 1 kHz for a variety of different applications
- Selectable filters:
- Low Pass 50/60Hz filter to perform measurements on equipment driven by Variable Frequency Drives (VFDs) or affected by high frequency noise
- Appliance Filter to conduct leakage current measurements on appliances
- No filter
- Selectable limits: 0.25 mA, 0.5 mA, 3.5 mA, 10 mA, 12 mA
- Max readings and hold function
- CAT III 600 V safety rating
