CT150A

Overview

The Hammond Manufacturing CT150A is a toroidal current transformer designed for industrial applications. It features a chassis mount style with wire leads for connection. The unit operates at a primary voltage of 600 V and supports a frequency range of 50 Hz/60 Hz. Key electrical specifications include a current ratio of 150:5, a power rating of 2 VA, and a primary current rating of 150 A. The device is constructed to handle high-current environments while maintaining accurate signal transformation for monitoring or protection circuits.

Feature Summary

• Toroidal core design for efficient magnetic coupling
• Chassis mounting configuration for secure installation
• Secondary leads terminated with crimped ring connectors

Applications

• Industrial current monitoring systems
• Electrical protection circuit integration
• High-current measurement instrumentation

Procurement Notes

Verify the specific secondary lead length and termination type against project requirements before ordering. Confirm that the 600 V primary voltage rating aligns with the system's operational limits. Ensure the chassis mounting dimensions fit the available enclosure space. Check for RoHS compliance documentation if environmental regulations apply to the deployment site.

Selection Notes

Select this model when a 150:5 ratio is required for currents up to 150 A. The 2 VA burden capacity must be sufficient for the connected metering or relay load. Consider the physical size and weight constraints for the installation panel. Verify compatibility with existing wiring harnesses due to the specific lead termination style provided by the manufacturer.

Part Context

This component belongs to the CT series of industrial current transformers from Hammond Manufacturing. The series offers various ratios tailored for different current levels while maintaining consistent toroidal construction and chassis mounting standards. These units are engineered for durability in demanding electrical environments, providing reliable isolation and signal conversion for control and monitoring purposes.

Replacement Considerations

Direct substitutes must match the 150:5 ratio, 2 VA rating, and 600 V primary voltage. Physical dimensions and mounting hole patterns should be verified to ensure interchangeability without modifying the chassis. Secondary lead lengths and connector types may differ between manufacturers, requiring adapter adjustments if exact replacement is not possible.
