ABB CMS122LA OPEN-CORE CURRENT SENSOR 18mm FOR RETROFIT OF MCBS & RCBOS, MEASURING RANGE 0.1-20A

The open-core current sensor is designed for retrofitting MCBs (S200, SMISSLINE) and RCBOs (SMISSLINE). It has a current measuring range of 0.1-20A and a current accuracy class 1. The peak value of the distorted wave-form is 6. It operates at a rated operational voltage of 690VAC/1500VDC, with a frequency of 50Hz. The operating temperature range is -25 to 70°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 9.6mm. The dimensions of the sensor are 38.9Hx17.4Wx41Dmm.
