5% off Zw43r-24 Auto Recloser 24kv with Ycch-42 Intelligent Controller

Product Description1.GeneralZW43R-24 Series Auto Recloser is rated voltage 24kV, three phase AC 50Hz outdoor distribution equipment. Mainly used for breaking, closing power system load current, overload current and short-circuit current. Applicable to substations and power distribution in industrial and mining enterprises for protection and control purposes, and frequent operation place for rural power grids.The circuit breaker has the features of small size, light weight, anti-condensation, maintenance and so on. Adapt to bad weather conditions and dirty environments. The vacuum interrupter of the circuit breaker adopts solid sealing technology, and the external insulation adopts silicone rubber sleeve; it has long life and high reliability; the operating mechanism can adopt a miniaturized, high-reliability spring mechanism, or an advanced permanent magnet mechanism. It can also be equipped with isolating switches and intelligent controllers, and can also be used as a sectioner or recloser to realize four remote control functions and power distribution automation.2.
