Air disconnect switch RNp III SA 24/4 03-035

Air disconnect switch – reliable connection in medium voltage networks

The RNp III SA 24/4 air disconnect switch is a key element of power infrastructure, designed for safe and efficient connection and disconnection of circuits in medium voltage overhead lines. The device is widely used in both new and modernized networks, ensuring reliability and long-term operation. The design of the disconnect switch allows for mounting in horizontal and vertical positions, increasing flexibility during installation and adaptation to specific terrain conditions.

Construction and application – solidity and functionality

The disconnect switch consists of three independent poles (current paths) mounted on a common steel beam, hot-dip galvanized to ensure high corrosion resistance. Silicone insulators guarantee excellent insulating properties even in harsh weather conditions. Main contacts made of tin-plated copper ensure low transition resistance and efficient current conduction. Additionally, the ability to mount an earthing module expands the functionality of the device, allowing for safe earthing of disconnected circuit parts.

The device is designed for operation in 15 and 24kV distribution networks, and its solid construction and high technical parameters guarantee safe and reliable operation for a long time. The RNp III SA 24/4 disconnect switch works perfectly in applications requiring frequent switching, as well as in installations with a constant load.
