SCTK681A Series 5A-630A RoHS Split Core Current Transformers with
0.333VAC or 0-500mA output
SCTK681A series split-core current transformer
- Test range: 5 to 630A AC input, output of 0 to 0.333V, 0 to 500mA
- Has been specially designed to facilitate their installation in new or already existing net works.
- They may be installed without opening any cable or bus-bar circuit.
- An internal precision resistor across the secondary winding of the CT provides a low safe voltage output.
- It can save time and the installation costs.
Applications:
- Relay protection device.
- Current and power measurement for electric motors, lighting, air compressor,heating and ventilation system, air-condition equipment and automation – control system.
- Current measurement, monitoring and protection for electrical wiring and equipment.
