SCCT 120/80 500/5A VA 2.5 CL 0.5 -CE

Current Sense Transformers Overview

The SCCT 120/80 500/5A VA 2.5 CL 0.5 -CE is a split-core current transformer manufactured by Selec Controls USA Inc. Designed for electrical energy monitoring, this device features a split core construction that allows installation around existing busbars or cables without disconnecting the primary circuit. It provides an isolated secondary output of 5A corresponding to a primary rating of 500A. The unit is rated at 2.5 VA burden and maintains a Class 0.5 accuracy level, ensuring precise measurement for billing and power quality analysis applications.

Current Sense Transformers Feature Summary

• Split-core design enables non-intrusive installation on live conductors
• Provides galvanic isolation between primary high-voltage circuits and secondary metering equipment
• Delivers standardized 5A secondary current output proportional to primary load
• Ensures high measurement precision with Class 0.5 accuracy rating

Current Sense Transformers Applications

• Integration with digital energy meters for commercial and industrial power monitoring
• Electrical panel retrofitting where cable disconnection is impractical
• Power quality analysis and harmonic distortion measurement systems
• Demand monitoring and load management in facility infrastructure

Current Sense Transformers Procurement Notes

Verify that the specific order includes the CE marking suffix as indicated in the model designation to ensure compliance with European safety and electromagnetic compatibility directives. Confirm that the physical aperture diameter of the split core matches the outer diameter of the conductor or busbar intended for measurement. Ensure the connected burden does not exceed the 2.5 VA rating to maintain the specified Class 0.5 accuracy during operation.

Current Sense Transformers Selection Notes

Select this component when non-invasive installation is required for existing electrical infrastructure. Choose based on the primary current rating of 500A matching the maximum expected load. Verify that the downstream instrumentation accepts a 5A input signal. Ensure the application environment supports the operational temperature range and that the split-core mechanism can securely clamp around the target conductor size.

Current Sense Transformers Part Context

This current transformer belongs to Selec Controls' range of passive sensing components used in electrical distribution networks. It serves as a critical interface between high-current primary circuits and low-current secondary measurement devices. The product facilitates accurate data acquisition for energy management systems without requiring system shutdowns during installation.

Current Sense Transformers Replacement Considerations

Substitute only with split-core current transformers sharing identical primary ratings (500A), secondary output (5A), and accuracy class (0.5). Verify mechanical compatibility regarding the split-core aperture size and mounting method. Ensure the replacement unit meets the same burden rating (2.5 VA) and regulatory certification requirements.
