Product Description

The SCTK667B series double-screw split-core current transformer is designed for current measurement and monitoring in new or existing power distribution networks. Measuring range is 5A to 3000A. The product uses a split-core structure that allows quick installation without disconnecting or removing cables or busbars. The wide window design accommodates large-diameter cables or busbars. Double-screw fastening ensures secure and reliable installation. The secondary winding has a built-in precision parallel resistor, providing a safe low-voltage output without the need for external sampling resistors. Multiple sizes are available to adapt to various existing installation conditions. It is widely used for current measurement, monitoring, and protection in power lines and equipment, as well as current and power measurement for motors, lighting, air compressors, HVAC, and automation control systems, as well as energy monitoring and relay protection devices.

FAQ

Q: What are the advantages of double-screw fastening?

A: Double-screw fastening ensures the transformer remains securely locked onto the cable or busbar after installation. It will not loosen or shift due to vibration or external forces, ensuring safe and reliable installation. Compared to snap-on structures, double-screw fastening provides stronger clamping force, suitable for high-current and high-vibration environments.

Q: What is the function of the built-in precision resistor?

A: The secondary winding has a built-in precision parallel resistor. It converts the current signal directly into a safe low-voltage output, eliminating the need for external sampling resistors. This simplifies installation, improves safety, and saves component costs and installation space.

Q: What window sizes are available for this product?

A: The wide window design accommodates large-diameter cables or busbars. Multiple sizes are available to adapt to various existing installation conditions. For specific window dimensions, please refer to the product datasheet or contact our sales team.
