Product Description

The SCTK731 series split-core current transformer is designed for current measurement and monitoring in new or existing power distribution networks. The product uses a split-core self-locking structure that allows quick installation without disconnecting or removing cables or busbars. The wide window design accommodates large-diameter cables or busbars.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 the self-locking structure?

A: The self-locking structure 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. Operation is simple, and no special tools are required for installation or removal.

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 applications can the 5-5000A measuring range meet?

A: The wide 5-5000A measuring range covers various applications from small to medium current equipment to large industrial power distribution systems, including current monitoring for motors, lighting, air compressors, HVAC, and main distribution lines.
