The 38kV 25kA MV Recloser is engineered to ensure uninterrupted power distribution in demanding outdoor environments, specifically designed for pole-mounted applications in medium-voltage networks. With a robust 25kA short-circuit breaking capacity and full compliance with IEC 62271-111 and ANSI C37.106 standards, this recloser delivers lightning-fast fault detection (<50 ms) and automatic reclosing capabilities, minimizing service disruptions for end-users.
