The AR-3S series circuit reclosers are recently-developed pole-mounted intelligent vacuum circuit reclosers of a new generation, which absorb the advanced domestic and foreign technologies adopted by our company, embody the design concept of being "intelligent, energy-saving, environemntally-friendly and maintenance-free" and comply with the actual conditions of China's power distribution network and the construction requirements of smart grid. These products can be used as switches at the 10kV outgoing line of substation as well as pole-mounted switches for power distribution networks. This product integrates such functions as control, protection, measurement, fault positioning, online monitoring and synchronous closing. With full functions and high digitalized and intelligent degree, they are top choices for equipment of power distribution network automation and intellectualization process.
This product conforms to IEC60044-1, IEC60060, IEC60068-2, IEC60099-4, IEC60255-27, IEC60270, IEC60280.1, IEC60529, IEC60694, IEC60815-1, IEC60870-5-101, IEC61000-4, IEC61243-5, IEC62271, standards, etc.
