Overview
The Hammond Manufacturing CT200A is a toroidal current transformer designed for chassis mounting within the CT series. It features a primary current rating of 200 A and a secondary output of 5 A, establishing a 200:5 turns ratio. The unit supports a maximum primary voltage of 600 V and has a power rating of 2 VA. Physical dimensions include a length of 4.25 inches, width of 1.75 inches, and height of 4.75 inches. Termination is achieved via wire leads.
Feature Summary
- Toroidal core construction provides non-invasive current sensing capabilities.
- Chassis mount design facilitates secure installation in industrial control panels.
- Secondary leads are supplied with crimped ring connectors for straightforward circuit integration.
Applications
- Industrial electrical metering systems
- Power monitoring equipment
- Control panel current sensing
Procurement Notes
Verify that the application requires a 200:5 ratio and 2 VA burden capacity to ensure compatibility with downstream instrumentation. Confirm chassis mounting space accommodates the specified physical dimensions. Ensure the primary conductor fits through the toroidal aperture without obstruction. Check lead length requirements against the standard 24-inch insulated secondary leads provided.
Selection Notes
Select this model when a robust, high-current toroidal solution is needed for chassis-mounted installations. Compare against the CT300A if higher primary current ratings are required. Consider the 2 VA power limit when calculating total burden impedance for connected meters or relays. Verify insulation class and voltage rating match the system's 600 V maximum operating conditions.
Part Context
The CT200A belongs to Hammond Manufacturing’s CT series of industrial current transformers. This series specializes in toroidal designs for accurate current measurement in heavy-duty environments. The component serves as a critical interface between high-current primary circuits and low-current secondary measurement devices, ensuring isolation and signal accuracy.
Replacement Considerations
The CT300A is a documented substitute offering a 300:5 ratio and 10 VA rating. Verify that the increased current capacity and power rating do not conflict with existing instrument specifications before substitution.
