Air disconnect switch RNM III SA 24/4S 03-059

Air disconnector – reliable protection for medium voltage networks

The RNM III SA 24/4S air disconnector is a key element of power infrastructure, designed for the safe switching on and off of medium voltage circuits. This device finds application in both new installations and modernized distribution networks. Its modular design and the ability to configure it with different types of insulators make it a versatile solution tailored to the specific needs of the installer and user.

Design and application

The RNM III SA 24/4S is characterized by a three-pole design, which ensures simultaneous disconnection of all phases of the circuit. This is particularly important in emergency situations when quick and reliable power disconnection is crucial for safety. The device is designed for aerial mounting, which facilitates its installation and maintenance. Thanks to the use of silicone insulators (S), the disconnector exhibits high resistance to atmospheric conditions and pollution, which translates into a long service life and minimal operating costs.

Advantages and benefits

• Versatility: Possibility of use in various network configurations thanks to the modular design.
• High reliability: Solid construction and precise workmanship guarantee trouble-free operation for a long time.
