The W2 series intelligent air circuit breaker (hereinafter referred to as circuit breaker) is suitable for distribution networks with frequency of AC 50Hz, rated working voltage up to 690V and rated current ranging from 200A to 1600A. It's used to distribute electrical energy and protect lines and power equipment from overload, short circuit, undervoltage, single-phase grounding(leakage) and other faults. The circuit breaker has intelligent protection function and precise selective protection, can improve power supply reliability and avoid unnecessary power outages. Meanwhile, it has open type communication interface, which is convenient for fieldbus connection, and can be used for four remote operations to meet the requirements of the control center and automation system. Equipped with corresponding leakage transformer and intelligent controller, leakage protection can be achieved.
The circuit breaker complies with GB14048.1-2012 Low-voltage switchgear and controlgear-Part 1: General rules; And GB14048.2-2008 Low-voltage switchgear and controlgear-Part 2: Circuit breakers; GB14048.4-2020 Low-voltage switchgear and controlgear-Part 4-1:Contactors and motor-starters-Electromechanical contactors and motor-starters( Including motor protector )
