The open-core current sensor is designed for pro M and SMISSLINE installation devices and features twin terminals. It has a current measuring range of 0.1-80A and a current accuracy class of 1. The peak value of the distorted wave-form is = 1.5. This sensor has a rated operational voltage of 690 VAC/1500 VDC, with a frequency of 50 Hz. It can operate in temperatures ranging from -25 to 70 deg C. The CMS sensors are capable of monitoring and measuring all types of current - alternating (AC), direct (DC), or mixed (TRMS) currents. Each sensor is equipped with its own microprocessor for signal processing. The maximum diameter of the cable that can be used with this sensor is 9.6 mm. The dimensions of the sensor are 26.5Hx17.4Wx41D mm.
