Product Description

The SCTK663 series split-core current transformer is designed for retrofit installation needs in existing power distribution networks. The product uses a split-core structure that allows quick installation without disconnecting or removing cables or busbars. It is secured with cable ties for reliable and firm fixing, significantly reducing labour installation costs. Two window sizes are available: 25mm and 45mm, suitable for different cable diameter requirements. It is widely used in HVAC temperature control, power management, building automation systems, motor current measurement, lighting, and air conditioning equipment current monitoring.

Wire Gauge: It is much better to oversize your CT than to undersize it. Please measure your wire diameter in millimeters, rather than use the MCM wire size because the insulation thickness varies materially from one wire manufacturer to the next.

FAQ
Q: How to choose between 25mm and 45mm windows?

A: The 25mm window is suitable for smaller cables (outer diameter ≤25mm). The 45mm window is suitable for larger cables or busbars (outer diameter ≤45mm). When selecting, please choose the appropriate window size based on the outer diameter of the cable under test.

Q: How to choose between 0-10V and 0-5A outputs?

A: 0-10V output is suitable for control systems that require voltage signals (such as PLC, DCS, building controllers). 0-5A output is suitable for traditional current-input measurement instruments and protection devices. Please choose based on your equipment input interface.

Q: What are the advantages of cable tie fixing?

A: Cable tie fixing requires no special tools, making installation simple and quick. It ensures the transformer is securely fixed on the cable and will not shift due to vibration or external forces. It is suitable for batch installation and on-site construction.
