SCCT 160/80 2000/5A VA15 CL 0.5 -CE

Current Sense Transformers Overview

The SCCT 160/80 2000/5A VA15 CL 0.5 -CE is a split-core current transformer manufactured by Selec Controls USA Inc., designed for electrical energy monitoring and protection applications. This specific model features a primary rated current of 2000 Amperes and a secondary rated current of 5 Amperes, providing a transformation ratio of 400:1. The device is engineered with a Class 0.5 accuracy rating, ensuring precise measurement within specified tolerance limits for billing and high-precision metering tasks. It supports a maximum burden of 15 Volt-Amperes (VA), allowing compatibility with various standard panel meters and data acquisition systems. The unit incorporates a split-core design, facilitating installation on existing busbars or cables without the need to disconnect power lines, thereby enhancing safety and reducing downtime during retrofit projects.

Current Sense Transformers Feature Summary

• Split-core construction enables non-intrusive installation on live conductors without circuit interruption
• Class 0.5 accuracy rating ensures reliable performance for precision metering and billing applications
• High primary current capacity of 2000A accommodates heavy industrial load monitoring requirements
• Standard 5A secondary output provides direct compatibility with conventional analog and digital panel meters

Current Sense Transformers Applications

• Industrial electrical panel energy monitoring and power quality analysis
• Commercial building utility sub-metering and revenue-grade billing systems
• Electrical distribution network protection relay input circuits
• Retrofitting existing switchgear for modernized energy management integration

Current Sense Transformers Procurement Notes

Verify that the physical aperture diameter of the split core matches the outer diameter of the conductor or busbar in use. Confirm that the connected burden does not exceed the 15 VA rating to maintain the specified Class 0.5 accuracy. Ensure the system polarity markings align correctly with the downstream metering device to prevent negative reading errors. Check for regional certification compliance requirements if the equipment is deployed outside standard North American jurisdictions.

Current Sense Transformers Selection Notes

Select this component when monitoring currents up to 2000A with high precision requirements in existing infrastructure where cable disconnection is impractical. Consider alternative models if the conductor size exceeds the available split-core opening or if higher accuracy classes such as 0.2 are mandated for specific regulatory standards. Evaluate the ambient temperature range and insulation voltage ratings against the specific installation environment to ensure long-term operational reliability and safety compliance.
