Air disconnect switch RNMp III SA 24/4Ko 03-083

Air disconnect switch – reliable protection for medium voltage lines

The RNMp III SA 24/4Ko air disconnect switch is a key element of power infrastructure, designed for the safe disconnection and connection of medium voltage circuits. This device is used both in new installations and during the modernization of existing networks. Its modular design and the possibility of mounting on poles make it a versatile solution for power engineers and installers.

Design and application

The RNMp III SA 24/4Ko disconnect switch is characterized by an asymmetrical three-pole construction, with a common support beam and a common drive for all poles. This design ensures simultaneous operation of all phases, which is important for the safety and reliability of the network. It is made of high-quality materials, which guarantees its durability and resistance to weather conditions. Designed for vertical mounting, which facilitates its integration with existing pole infrastructure.

The current path of each pole consists of main contacts, providing effective circuit interruption. Thanks to the use of composite insulators (marked "Ko"), the disconnect switch exhibits high resistance to contamination and environmental conditions, which translates into minimal maintenance requirements. Composite insulators are lighter than porcelain ones, which facilitates installation and reduces the load on the pole structure.
