SCCT 30/20 100/5A VA 1.5 CL 3 -CE

Current Sense Transformers Overview

The SCCT 30/20 100/5A VA 1.5 CL 3 -CE is a current transformer manufactured by Selec Controls USA Inc., designed for electrical energy measurement applications. This device features a primary current rating of 100 Amperes and a secondary output of 5 Amperes, facilitating the connection to standard ammeter or metering equipment. The unit is rated at Class 1.5 accuracy, ensuring reliable performance in commercial and industrial power monitoring systems. It supports a burden capacity of 1.5 Volt-Amperes (VA) and complies with CE regulatory standards for safety and electromagnetic compatibility within applicable markets.

Current Sense Transformers Feature Summary

• Provides accurate step-down conversion of high primary current to standardized low secondary current for metering
• Ensures galvanic isolation between high-voltage primary circuits and low-voltage measurement devices
• Delivers Class 1.5 accuracy performance suitable for general commercial energy monitoring applications

Current Sense Transformers Applications

• Commercial building energy management systems
• Industrial power distribution panels
• Electrical substation metering points

Current Sense Transformers Procurement Notes

Verify that the required primary current matches the 100A specification and that the connected metering device operates on a 5A secondary input. Confirm that the system burden does not exceed the 1.5 VA rating to maintain Class 1.5 accuracy. Ensure the CE marking aligns with local regulatory requirements for installation regions. Check physical mounting dimensions against panel space constraints prior to ordering.

Current Sense Transformers Selection Notes

Select this model when a 100:5 ratio is required for existing 5A secondary instrumentation. Consider higher accuracy classes if revenue-grade billing is necessary, as Class 1.5 is intended for monitoring rather than precise billing. Evaluate insulation voltage ratings against the system's nominal voltage to ensure adequate dielectric strength. Compare physical form factors with alternative manufacturers if specific mounting hardware or spatial limitations exist in the switchgear design.

Current Sense Transformers Part Context

Current transformers are essential components in electrical infrastructure, serving as the interface between high-power distribution networks and low-power control or measurement devices. They enable safe monitoring of load conditions without exposing sensitive electronics to dangerous voltages. Manufacturers like Selec Controls produce these devices to meet international standards for accuracy and safety, supporting the transition toward smarter grid management and efficient energy usage in modern facilities.
