Overview
The Hammond Manufacturing CT250A is an industrial toroidal current transformer designed for chassis mounting. It features a primary-to-secondary current ratio of 250:5, providing a secondary rated current of 5 A. The device supports a maximum primary voltage of 600 V and operates at frequencies of 50 Hz or 60 Hz. With a power rating of 10 VA, it utilizes wire leads for termination. The unit measures 4.75 inches in height, 4.25 inches in length, and 1.75 inches in width, weighing approximately 698.5 g.
Feature Summary
- Non-invasive solid core toroidal design for direct conductor insertion
- Chassis mount configuration with wire lead terminations
- Industrial-grade construction suitable for high-voltage environments
Applications
- Industrial electrical panel monitoring
- Power distribution system metering
- Protective relay input circuits
Procurement Notes
Verify the specific current ratio and physical dimensions against the official Hammond Manufacturing datasheet prior to integration. Confirm that the application voltage does not exceed the 600 V primary rating. Ensure the load burden remains within the 10 VA limit to maintain accuracy. Check RoHS compliance status if environmental regulations apply to the deployment region.
Selection Notes
Select this component when a 250:5 transformation ratio is required for chassis-mounted installations. Compare the 10 VA power rating against the connected instrument burden to ensure adequate capacity. Consider the physical envelope of 4.75 x 4.25 x 1.75 inches for enclosure space planning. Verify compatibility with the existing wiring harness due to the wire lead termination style.
Part Context
This part belongs to the CT series of industrial current transformers manufactured by Hammond Manufacturing. The series offers various ratios to accommodate different current levels while maintaining consistent toroidal geometry and chassis mounting standards. The CT250A specifically addresses applications requiring measurement of currents up to 250 A with a standardized 5 A output.
