Product Description
The W2 series air circuit breaker (hereinafter referred to as the breaker) is designed for AC 50Hz circuits with rated voltages of 400V and 800V and a rated current of up to 1600A. Its primary functions include distributing electrical energy and protecting circuits and power supply equipment from overload, undervoltage, short circuits, and single-phase grounding faults. With advanced intelligent and selective protection features, this breaker is ideal for use in power stations, factories, mines (for 800V), and modern high-rise buildings, particularly within the distribution systems of smart buildings. This breaker complies with IEC60947-2 and GB14048.2 standards.
