WCW1 Intelligent Universal Air Circuit Breaker

Overview

WCW1 series intelligent universal low-voltage circuit breakers are suitable for distribution networks with AC 50Hz, rated voltage AC400V/690V, and rated current 200A ~ 6300A. They are used to distribute electric energy and protect lines and power equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has intelligent protection functions and precise selective protection, which can improve power supply reliability and avoid unnecessary power outages. At the same time, it has an open communication interface and can perform “four remote controls” to meet the requirements of the control center and automation system. Compliant Standards:IEC60947-2

Operating Conditions

▲ Temperature: The upper limit value shall not exceed +40°C, the lower limit value shall not be lower than -5℃, and the average value of 24h shall not exceed +35℃; Note: The user shall consult with our company for the working conditions with the upper limit value exceeding +40℃ or the lower limit value lower than -10℃ or -25℃;

▲ Altitude: ≤2000m;
