Auto Recloser with Intelligent Controller

Model ZW43R-24

The circuit breaker's auto recloser with intelligent controller uses solid sealing technology, and silicone rubber sleeves are used for external insulation. It has a long lifespan and great dependability. The operating mechanism of the auto recloser can be either an advanced permanent magnet mechanism or a miniature, highly reliable spring mechanism. In order to achieve four remote control capabilities and power distribution automation, it can also be fitted with intelligent controllers and isolating switches. It can also be utilized as a sectioner or recloser.
