Product Details

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
