Amprobe ALC-110 Specifications
ALC-110
Leakage Current Clamp
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
• Low influence of external low frequency
magnetic fields: @ I
≤ 30 A/m, operating class 2
• True-rms measurements for accuracy when
measuring complex, non-sinusoidal waveforms
• Mechanical jaw lock to assure accuracy of low
current measurements, avoiding disturbance
from measured wires and magnetic fields;
jaw opening 1.2 in (30 mm)
• 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, including
industrial and railway
• 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
• High safety rating: CAT III 600 V
• Battery-saving design with an auto backlight off
and auto power off
N: 3.500 mA – 600.0 mA

Applications
• 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
• Check a system for an electrical break of
insulation where current is flowing to the ground
• Where industrial leakage current testing
is required

Safety Certification
All Amprobe tools, including the Amprobe ALC-110, are rigorously tested
for safety, accuracy, reliability, and ruggedness in our state-of-the-art
test lab. In addition, Amprobe products that measure electricity are listed by a
3rd party safety lab, either UL or CSA. This system assures that Amprobe products
meet or exceed safety regulations and will perform in a tough, professional
environment for many years to come.
