The SCTK661 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 mechanical sizes are available with high customisability, adapting 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, and other applications.

Features:
  • The structure of the self-locking, safe, easy to install, portable
  • Split core current transformer with interleaved joint and hinge structure
  • Test hole series size clamp leaker AC current transformer
  • Wide inner window, allowing clamping of big cables or bus-bars
  • Test range: 0.5 to 630A AC input, output of 0 to 0.333V, 0 to 500mA
  • Suitable for single-phase electricity meter as well as anti-tampering electricity meter
  • Wide range of sizes to accommodate all the existing installations
  • Various mechanical dimensions, highly custom-tailored
  • It can save time and the installation costs.
Applications
  • Power line current measurement and monitoring
  • Electrical equipment current protection
  • Motor current and power measurement
  • Lighting system power monitoring
  • Air compressor current monitoring
