| Product List |
The SCTK660C 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. 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.

Notes: Product specifications can be customized
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 (0.333V) or standard current signal (0-500mA), eliminating the need for external sampling resistors. This simplifies installation, improves safety, and saves component costs and installation space.
Q: How to choose the output signal type?
A: 0.333V output is suitable for electronic energy meters, PLCs, and voltage-input measurement instruments. 0-500mA output is suitable for control systems and traditional measurement equipment that require current signals. Please choose based on your measurement equipment input interface.
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
