Overhead disconnect-earthing switch RUNp III SA 24/4S 03-044

Aerial disconnect-earthing switch – reliable connection and safety

The RUNp III SA 24/4 aerial disconnect-earthing switch is a device designed for the safe and efficient suspension of insulated aerial conductors AsXS(n) with cross-sections from 16 mm² to 95 mm². The construction of this disconnect switch, based on solid materials and precise workmanship, guarantees long-lasting and trouble-free operation in various weather conditions. It is a key element of electrical infrastructure, ensuring both installation safety and ease of maintenance.

Construction and application – combining functionality with durability

The disconnect switch latch is made of durable, hot-dip galvanized profiled sheet metal, providing high corrosion resistance. The M8 butterfly screw, also hot-dip galvanized, enables quick and secure mounting. The rubber insert, resistant to UV radiation and weathering, ensures stable mounting of cables with different cross-sections. This disconnect switch is primarily used with standard hook bolts, enabling optimal use of existing infrastructure. The three-pole design with a common base and drive facilitates the simultaneous closing and opening of all poles, which translates to operational efficiency.

Key features and benefits for professionals and users

• Durability and corrosion resistance: The hot-dip galvanized construction provides long-lasting protection against the effects of the weather.
