Dwyer Series CCT40/50 Current Transformer

Product Description

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.

FAQ

Question

What is the proper way to wrap the wire around the Current Transformer #CCT40-200?

Answer

If the current running through your wire is high enough to be detected by the model CCT you have, then you can simply single wrap it as you have shown in the attached PDF you provided. However, if the current is too low to be detected, then you would want to wrap the wire around until the current is high enough to be detected. Here is a link to the service manual for our Series SCT Current Transformer that explains this concept better, Series SCT Instruction Manual. See Figure 4.
