SCTK681A Series 5A-630A RoHS Split Core Current Transformers
The SCTK681A series split-core current transformer is designed for current measurement and monitoring in new or existing power distribution networks. Measuring range is 5A to 630A, with frequency range 50-2000Hz.The product uses a split-core structure that allows quick installation without disconnecting or removing cables or busbars. This significantly reduces installation cost and time.The secondary winding has a built-in precision parallel resistor, providing a safe low-voltage output of 0.333VAC or 0-500mA without the need for external sampling resistors.Ratio error: ≤±1.0%. Phase angle error: ≤±60 minutes. Dielectric strength: 2.5KV/1mA/1 minute. RoHS compliant.It is widely used in relay protection devices, motor current and power measurement, lighting, air compressors, HVAC, automation control systems, and power distribution line monitoring.

FAQ
Q: Does the split-core current transformer require power-off or cable removal during installation?
A: No. The SCTK681A series uses a split-core structure with a core that opens and closes. It can be installed without disconnecting or removing any cables or busbars. This feature makes it especially suitable for retrofit projects and applications where power cannot be turned off, significantly reducing installation costs and time.
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 (0.333VAC) or standard current signal (0-500mA). This eliminates the need for external sampling resistors. This design simplifies installation, improves safety, and saves component costs and installation space.
Q: What applications can the ≤±1.0% ratio error meet?
A: The ±1.0% ratio error meets the accuracy requirements of most industrial power monitoring, equipment protection, energy management, and automation control applications. For higher accuracy requirements such as energy metering, please consult us for models with higher accuracy classes.
