The SCTK732B 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 structure that allows quick installation without disconnecting or removing cables or busbars. The secondary winding is evenly distributed around the core circumference, providing low leakage flux and stable performance. The ABS flame-retardant plastic housing provides good insulation protection. A built-in precision parallel resistor provides 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 devices.
