Air disconnect switch RNMp III SA 24/4So 03-087

Air disconnect switch – reliable protection for medium voltage networks

Air disconnect switch RNMp III SA 24/4So is a key element of power infrastructure, designed for the safe switching on and off of medium voltage circuits. This device finds application both in transformer stations and on overhead lines, providing effective isolation and protection against overloads and short circuits. The design of the disconnect switch allows for installation in a vertical position, facilitating servicing and maintenance.

Construction and application

The RNMp III SA 24/4So disconnect switch is characterized by a three-pole modular construction with an asymmetrical design, ensuring stability and reliability of operation. A common support beam and drive for all poles guarantee simultaneous closing and opening of the circuits. The device is adapted to operate in harsh atmospheric conditions, in the temperature range from -40°C to +40°C and air humidity below 100%. The disconnect switch is mounted on overhead poles, and its design allows for cooperation with various types of insulators – porcelain, composite or silicone (the "S" version denotes silicone insulators).
