Small Volume CT Split Core Current Transducer Easy Installation Low Magnetic Circuit Loss
SCTK681B Series low voltage 5A~630A Input 333mV 500mV Output Split Coil Current Transformer,High Accuracy
The SCTK681B series of split core current transformer are designed for fast and easy installation.The split core design permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken offline and disconnected for CT installation.This method permits a safer,easier and portable current measurement. An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary
Features:
- Test range: 5 to 630A AC input
- Output of 0 to 500mA, 0 to 0.333V
- Iron core is divisible, with high accuracy and low magnetic circuit loss
- Elegant appearance, small volume, light weight, openable, easy installation
- It is convenient to install, need not to disassemble the bus, can be operated under live condition, and will not affect customers’ normal using
Applications:
- Current measurement, monitoring and protection for electrical wiring and equipment
- Current and power measurement for electric motors, lighting, air compressor, heating and ventilation system, air-condition equipment and automation.
- Current, power and energy monitoring device
- Relay protection device
