SCCT 30/20 300/5A VA 5 CL 3 -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 current rating of 300A and a secondary output of 5A. The device operates at frequencies between 50Hz and 60Hz with a maximum burden of 2.5VA. Designed for bus bar applications, it accommodates conductor rail sizes up to 20mm x 30mm. Physical dimensions are 91mm x 109.5mm. It holds CE certification.

Current Sense Transformers Feature Summary

• Split-core design facilitates installation without disconnecting primary conductors
• Provides electrical isolation between primary circuits and measurement equipment
• Supports standard 50Hz and 60Hz power system frequencies

Current Sense Transformers Applications

• Electrical panel metering systems
• Energy monitoring and management installations
• Industrial automation control circuits

Current Sense Transformers Procurement Notes

Verify that the specific ordering suffix matches the required accuracy class and burden rating. Confirm physical compatibility with existing bus bar dimensions before procurement. Ensure the split-core mechanism integrity is intact during shipping. Cross-reference the CE marking requirements against local regulatory standards for the intended deployment region.

Current Sense Transformers Selection Notes

Select this component when non-intrusive current measurement is required for bus bars or large conductors. Ensure the primary current range covers the expected load variations. Verify that the secondary burden does not exceed the rated VA limit. Consider the physical aperture size relative to the conductor cross-section to ensure proper fit and accurate transformation ratios.

Current Sense Transformers Part Context

This model belongs to the SCCT series of current transformers designed for precise current sensing in power distribution networks. It complements digital panel meters and energy monitors by providing isolated analog signals proportional to the primary line current. The series supports various accuracy classes for different application requirements.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing, verify that the new unit matches the 300/5A ratio, 2.5VA burden capacity, and physical aperture dimensions to maintain system compatibility.
