Air disconnect switch, modular - vertical 100A RNMp III SA 24/4/100 03-719

Modular air disconnect – reliable protection for medium voltage networks

Air disconnect RNMp III SA 24/4/100 is a device used to safely switch on and off circuits in overhead medium voltage lines. Its modular design and vertical construction facilitate installation and maintenance, and its solid construction guarantees long-lasting and trouble-free operation. The device is designed for use in both distribution networks and industry.

Design and application

The RNMp III SA 24/4/100 disconnect is characterized by a three-pole design, which ensures complete circuit isolation. The modular construction allows for flexible adaptation to different network configurations and easy replacement of individual elements in the event of a failure. Vertical mounting on a pole minimizes space occupied and facilitates access to the device during inspections. This is particularly important for installers who value convenience and speed of work.

The device finds application primarily in:

• Overhead medium voltage lines (24 kV) – as a disconnecting element enabling safe maintenance and repair work.

• Transformer stations – as a safety switch before starting work on the transformer or nearby.

• Medium voltage switchgear – as a protective element against overload and short circuit.

• Connections to the power grid – providing safe disconnection of the consumer from the grid in the event of a failure or the need to carry out work.

Advantages and benefits

• Modular design: Enables easy configuration and replacement of elements, reducing downtime during maintenance or repairs.

• Vertical mounting: Saves space on the pole and facilitates access to the device during inspections.

• Three-pole design: Ensures complete circuit isolation, increasing work safety.

• Durable construction: Guarantees long-lasting and trouble-free operation even in harsh weather conditions.

• Compatibility with various types of insulators: Possibility of using porcelain, silicone or composite insulators, adapting the device to specific installation requirements.

• Possibility of mounting with surge arresters: Additional protection against the effects of lightning strikes, protecting devices connected to the grid.

• Designed for direct mounting on the pole base: Simplified installation process, reduced mounting costs.

Thanks to these features, the RNMp III SA 24/4/100 disconnect is a reliable and effective solution for professionals involved in the construction and maintenance of power grids and for end-users looking for safe and durable protection for their electrical installations.
