SPCT 50/30 60/5 A VA 1 CL 5-CU-ROHS

Overview

The SPCT 50/30 60/5 A VA 1 CL 5-CU-ROHS is a bus bar current transformer manufactured by Selec Controls USA Inc. It features an inner dimension of 50x30 mm, accommodating specific busbar sizes. The device provides a current ratio of 60:5, with a rated secondary output of 5A. It operates within a frequency spectrum of 50Hz to 60Hz and supports a maximum operating voltage of 720V. The accuracy class is designated as Class 5, suitable for metering applications requiring standard precision.

Feature Summary

• Designed for use with different busbars via a 50/30 mm inner dimension
• Provides accurate current sensing with a 60:5 transformation ratio
• Supports standard industrial frequencies from 50Hz to 60Hz

Applications

• Industrial power distribution monitoring
• Electrical metering systems requiring 60A primary current sensing
• DIN rail mounted protection and control circuits

Procurement Notes

Verify the exact accuracy class (Class 5) and burden rating (VA 1) against specific meter requirements. Confirm that the 50x30 mm window matches the physical busbar dimensions in the installation environment. Ensure the 720V maximum voltage rating exceeds the system's line-to-line or line-to-neutral voltage. Check for compliance with local safety standards and RoHS directives if required for the project specifications.

Selection Notes

Select this component when a 60:5 current ratio is required for primary currents up to 60A. The 50/30 mm aperture dictates compatibility with specific busbar geometries. Consider the Class 5 accuracy limit for non-critical metering or general indication tasks. Verify that the VA 1 burden capability aligns with the connected instrument's input impedance to maintain measurement integrity within the specified frequency range.

Part Context

This model belongs to the SPCT series of current transformers from Selec Controls. These devices are typically designed for DIN rail mounting in electrical panels. The series offers various ratios and aperture sizes to accommodate different current levels and busbar configurations. The CU suffix indicates copper construction, while ROHS denotes environmental compliance.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the 50/30 mm aperture, 60:5 ratio, and Class 5 accuracy. Alternative models from other manufacturers must be evaluated based on identical electrical parameters and mechanical fit.
