Product Introduction
1.CR3100 Series Detachable Current Sensor Product Description:
The detachable current sensor CR3100 series includes four models: CR3109-1500, CR3110-3000, CR3111-3000, and CR3113-2000. It is an economical way to monitor current. The unique rotating shaft and lock ensure that the measured current line is not affected when closed. The secondary coil can produce a maximum voltage of 10VAC through a load resistor.
