Product Description
TOPRO hinged split-core current transformers KF series offer an excellent balance between function and accuracy. The quick release button makes the CT to fit with conductors（Cable/Wire）for precision current measurement easily, without cutting off the circuit. KF current transformer has advantages of bigger capacity and bigger mounting hole size, so they could be used in many power applications. The installer-friendly design ensures rapid installation in any environment.
Product Characteristics:
1.High accuracy: 0.5% from 10%-120% of rated current
2.Input current range: 5A-1000A AC (depending on the Models)
3.Safe,333mV output
4.Hinged split core design for quick installation without disconnecting the measured primary conductor.
5.Engineered for superior utility in crowded electrical panels
Applications:
1.Measurement, monitoring and protection for electrical circuit and instrument.
2.Current and power measurement for electric motors, lighting, air compressor, heating and ventilation system,
air-condition equipment and automation-control system.
3.Relay protection device.
4.Charging pile
5. Data center
