Dwyer CCT60/70 Series True RMS Current Transformers
Solid or Split Core, Field Selectable Range
The Series CCT60/70 True RMS Current Transformers are a low-cost alternative for 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 flange for quick installation
- Solid core or split core configurations
- Jumper selectable range
- True RMS
Applications
- BAS
- HVAC

Dimensional Information
Solid Core Diagram: Depicts a solid, U-shaped current transformer. Key dimensions include an overall width of approximately 2-29/32 inches (74.00 mm), a height of 3-1/2 inches (89.00 mm), and a depth of 1-17/64 inches (32.00 mm). The central aperture for the conductor measures Ø3/4 inches (Ø19.00 mm).
Split Core Diagram: Illustrates a current transformer designed with two halves that can be opened and clamped around a conductor. Key dimensions include an overall width of 3-1/2 inches (89.00 mm), a height of 2-3/4 inches (70.00 mm), and a depth of 2-7/16 inches (62.00 mm). The conductor openings are shown as two parts, each approximately Ø13/64 inches (Ø5.00 mm).
