Designed for operation within the 50Hz to 60Hz frequency range, this component features a free-hanging in-line mounting type with an inner diameter of 55mm. It provides a current ratio of 150:5 and adheres to the IEC 61869-2 standard. The unit offers a rated burden of 5VA and maintains a class of accuracy 1.

Feature Summary

• Non-invasive solid core design for easy installation around conductors
• Tape wound construction ensuring precision and reliability
• Free hanging in-line mounting configuration

Applications

• Industrial automation systems
• Power monitoring equipment
• Electrical control panels

Procurement Notes

Verify the specific part number against official Selec Controls documentation to ensure compatibility with existing system requirements. Confirm that the 55mm inner diameter accommodates the target conductor size. Ensure the 5VA burden rating matches the connected metering or protection device specifications. Validate that Class 1 accuracy meets the project's measurement tolerance standards before finalizing procurement.

Selection Notes

Select this model when a non-invasive solution is required for currents up to 150A with high accuracy needs. The 55mm aperture must be sufficient for the cable being monitored. Consider the 5VA burden capacity to ensure it supports the downstream load without exceeding limits. Verify that the operating frequency aligns with the 50Hz or 60Hz power supply in use.

Part Context

This component belongs to the Selec TWCT series of tape wound current transformers. These devices are engineered for industrial applications requiring precise current sensing. The series typically offers various ratios and burden options to suit different monitoring and protection scenarios within electrical infrastructure.

Replacement Considerations

Direct substitutes may include other Selec models from the TWCT series with matching 55mm inner diameters and similar accuracy classes. Ensure any replacement maintains the 150/5A ratio and 5VA burden rating to preserve system functionality.
