CCT50-203

Current Sense Transformers Overview

The Dwyer CCT50-203 is a solid-core current transformer from the Series CCT40/50, designed for measuring power and monitoring equipment operation. It features a jumper-selectable input range of 100/150/200 A and provides a 0 to 10 VDC analog output. The device is self-powered with an accuracy of 1%. It operates within a temperature range of -30 to 70°C (-22 to 158°F) and maintains performance in humidity conditions up to 95% relative humidity non-condensing.

Current Sense Transformers Feature Summary

• Solid-core construction for direct conductor insertion without breaking the circuit
• Field-selectable amperage range via internal jumpers for flexible installation
• Self-powered operation eliminating the need for external auxiliary voltage sources
• Integrated analog voltage output for direct connection to data acquisition systems

Current Sense Transformers Applications

• Monitoring fan motor current consumption
• Tracking pump operational status and load
• General power measurement in industrial control panels

Current Sense Transformers Procurement Notes

Verify that the specific part number CCT50-203 corresponds to the desired selectable range configuration. Confirm that the application environment remains within the specified temperature limits of -30 to 70°C. Ensure the connected receiving device accepts a 0-10 VDC signal input. Check for any physical mounting constraints related to the solid-core housing dimensions before finalizing the order.

Current Sense Transformers Selection Notes

Choose this model when a low-cost, self-powered solution is required for AC current monitoring. The jumper-selectable range allows one part number to cover multiple standard current ratings. It is suitable for applications where breaking the primary circuit is not feasible due to the solid-core design. Ensure the load impedance of the receiving instrument does not exceed the sensor's output capabilities.

Current Sense Transformers Part Context

This component belongs to the Dwyer Series CCT40/50 line of current transformers. These sensors are engineered as cost-effective alternatives for basic power monitoring tasks. The series emphasizes simplicity and reliability for continuous operation in industrial environments. The CCT50 variant specifically offers higher precision compared to lower-tier models in the same family.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 100/150/200 A selectable range and 0-10 VDC output. Verify compatibility with existing panel cutouts and busbar sizes. Ensure the replacement unit also supports self-powered operation if no auxiliary supply is available in the installation location.
