NOJA OSM Three Phase automatic circuit reclosers are designed for use on overhead distribution lines as well as distribution substation applications for all voltage classes up to 38kV.
The product is supplied complete with an RC control and communications cubicle. The RC control cubicle provides all the protection, data logging and communications functions in a single device. The OSM has been designed for use as a stand-alone device that is easily integrated into distribution automation and remote control schemes using the in-built communications capability.
The product has been extensively type tested by independent laboratories to ensure long life and reliability under the harshest environmental conditions. The OSM automatic circuit recloser is the only solid di-electric insulated recloser to provide controlled arc fault venting and the independent testing provides verification of this important safety feature.
