Description:
the Interrupter adopts " one shut technology", ceramic shell, CuWC as the contact material;is characterized by high insulation, low stop-flow, strong blowout ability, long life, smallsize etc, and has advantages as easy to maintain, no explosion risk,pollution-free and lownoise etc. Contactors assembled by it are used to control and protect the electricity transmission and distribution system in electrical, mechanical, chemical, metallurgy, mining and railway department, especially in frequent operation fields.
