Air disconnect switch - earthing, modular - vertical 100A RUNMp III SA 24/4/100 03-720

Aerial disconnect-earthing switch – reliable protection for medium voltage lines

This modular aerial disconnect-earthing switch RUNMp III SA 24/4/100 is a key element of power infrastructure, providing safe and efficient disconnection and earthing of medium voltage lines. The device's design, based on proven technology, guarantees high reliability and long life in demanding working conditions. It is a solution for both professional installers and network operators looking for solid and functional equipment.

Construction and application

The RUNMp III SA 24/4/100 disconnect-earthing switch is designed for vertical mounting on poles. The modular design allows for flexible adaptation to different network configurations and easy integration with other infrastructure elements. The device is used in transformer stations, aerial switchgear and medium voltage lines where effective disconnection and earthing of circuits are required during maintenance or emergency work. Thanks to the possibility of independently setting the poles in relation to each other while maintaining minimum distances, installation is simplified and adapted to the specifics of a given location.

Key features and benefits

• Modular design: Enables flexible adaptation to specific installation needs and easy mounting on a pole.
• Vertical mounting: Ensures optimal use of space and structural stability.
• Three-pole design: Guarantees complete circuit disconnection in a single operating cycle.
• Durable insulation: Available versions with porcelain, silicone or composite insulation – choosing the right material allows you to adapt the device to the prevailing environmental conditions.
• Compatibility with manual and motor drives: Enables remote control of the disconnect switch, increasing operator comfort and safety.
• Possibility of installing surge arresters: Increases the level of protection of the installation against the effects of atmospheric discharges.
• Asymmetrical three-pole construction: Ensures stability and reliable operation in various operating conditions.
• Adaptation for direct mounting on the pole base: Simplified installation without the need for additional mounting elements.

Remember to choose the appropriate type of insulator (porcelain, silicone or composite) depending on the specific environmental conditions prevailing at the installation site. When installing the modular disconnect switch, provide the top diameter of the spun pole for proper structural fit.
