SERIES CCT40/50
PROCESS CONTROL
CURRENT TRANSFORMERS
Solid or Split Core, Field Selectable Range
The Series CCT40/50 Current Transformers are a low cost alternative for measuring
power and monitoring the operation of fans, pumps, or other equipment. For use on
existing installations, split core models can be installed without disconnecting cables.
Each model offers three jumper selectable ranges and a choice of three different
outputs.
FEATURES/BENEFITS
• Integral mounting ange for quick installation
• Solid core or split core congurations
• Jumper selectable range

Current Transformers/
SERIES CCT60/70
TRUE RMS CURRENT TRANSFORMERS
Solid or Split Core, Field Selectable Range
The Series
providing true RMS outputs on distorted AC waveforms. True RMS outputs are ideal
for nonlinear loads or noisy circuits. For existing installations, split core models can
be installed without disconnecting cables. Each model offers three jumper selectable
ranges to reduce the risk of ordering the wrong model.
FEATURES/BENEFITS
• Integral mounting ange for quick installation
• Solid core or split core congurations
• Jumper selectable range
• True RMS
