SCCT 30/20 300/5A VA 2.5 CL 0.5 -CE

Current Sense Transformers Overview

The SCCT 30/20 is a split-core current transformer manufactured by Selec Controls USA Inc. It features a primary rating of 300 A and a secondary output of 5 A, with a burden capacity of 2.5 VA. The device adheres to Class 0.5 accuracy standards and carries CE certification for compliance with European regulations. Designed for split-core installation, it allows for non-intrusive integration into existing electrical circuits without disconnecting conductors.

Current Sense Transformers Feature Summary

• Split-core design enables installation around existing busbars or cables without circuit interruption
• Provides accurate current transformation from 300 A primary to 5 A secondary output
• Class 0.5 accuracy ensures reliable measurement performance for metering applications

Current Sense Transformers Applications

• Integration with energy meters for commercial electricity billing
• Monitoring loads in industrial distribution panels
• Power quality analysis in facility management systems

Current Sense Transformers Procurement Notes

Verify that the specific order includes valid CE marking documentation and meets local regulatory requirements for electrical safety. Confirm that the split-core aperture diameter matches the physical dimensions of the conductor or busbar being monitored to ensure proper magnetic coupling and measurement accuracy.

Current Sense Transformers Selection Notes

Select this model when a non-invasive monitoring solution is required for high-current circuits up to 300 A. Ensure the connected measuring instrument supports a 5 A input range and does not exceed the 2.5 VA burden limit. Consider the physical size of the split core relative to the available space around the conductor during installation.

Current Sense Transformers Part Context

This component belongs to the series of split-core current transformers designed for seamless retrofitting into electrical infrastructure. Unlike solid-core variants, these units allow for maintenance and expansion of monitoring systems without powering down the associated electrical circuits, providing operational continuity during installation.

Current Sense Transformers Replacement Considerations

When replacing existing units, verify that the new transformer shares identical primary-to-secondary ratios (300:5 A) and burden ratings (2.5 VA). Ensure the split-core mechanism accommodates the same conductor diameter to maintain consistent magnetic flux linkage and measurement precision.
