SPCT 50/30 200/5 A VA 3 CL 1-CU-ROHS

Overview

The SPCT 50/30 200/5 A VA 3 CL 1-CU-ROHS is a current sense transformer manufactured by Selec Controls USA Inc. Designed for DIN rail mounting, this component operates within a frequency range of 50Hz to 60Hz. It features a primary current rating of 200 Amperes and a secondary output of 5 Amperes. The unit supports a burden capacity of 3 Volt-Amperes (VA) with Class 1 accuracy. Physical dimensions are approximately 1.969 inches in length and 1.693 inches in width. It provides isolation up to 3kV AC for one minute and has a maximum operating voltage of 720V.

Feature Summary

• DIN rail mounting design for secure installation
• Class 1 accuracy for precise current sensing
• High isolation voltage capability
• RoHS compliant construction

Applications

• Industrial power monitoring systems
• Electrical distribution panels
• Energy metering equipment
• Current protection circuits

Procurement Notes

Verify the specific part number against official Selec Controls documentation to ensure compatibility with existing system requirements. Confirm that the 200A primary rating and 3VA burden capacity match the intended application load. Check for regional compliance certifications such as CE if required for the deployment location. Ensure storage temperatures remain between -5°C and +50°C when not in use.

Selection Notes

Select this model when a 200:5 current ratio is required for DIN rail mounted applications. Consider the 3VA burden limit when connecting secondary loads. Verify that the 720V maximum operating voltage suits the circuit environment. Ensure the 50Hz to 60Hz frequency range aligns with the power supply characteristics. Compare physical dimensions against available panel space constraints.

Part Context

This component belongs to the SPCT series of current transformers from Selec Controls. The series includes variants with different primary ratings such as 75A, 250A, and 400A. All models share similar mounting styles and operational principles but differ in current handling capabilities and burden ratings. The SPCT series is designed for industrial environments requiring reliable current measurement.

Replacement Considerations

Direct substitutes include other SPCT series models like SPCT 50/30 250/5 A VA 3 CL 1-CU-ROHS or SPCT 50/30 75/5 A VA 1 CL 1-CU-ROHS, provided the current ratio and burden specifications meet the application needs. Cross-manufacturer replacements require matching electrical parameters and mechanical form factors.
