m-Smart Auto Reclosers
m-Smart Auto Reclosers are solid insulated reclosers with vacuum interrupters, encapsuled in hydrophobic cycloaliphatic epoxy resin and magnetic actuator mechanism, built for harsh outdoor unmanned power distribution applications. These auto reclosers are aimed to the improve the system reliability, downtime and cost of ownership. Keeping operator safety at high priority, conventional instrument transformers are replaced by failure proof current and voltage sensors.
