Air disconnect switch, frame-type - horizontal 100A RN III SA 24/4/100 03-703

Air disconnect switch – reliable protection for medium voltage networks

The RN III SA 24/4/100 air disconnect switch is a component used to safely switch on and off medium voltage electrical circuits. It is a key component in transformer stations, switchgear and overhead lines, providing protection for equipment and personnel. The frame construction, designed for horizontal mounting, guarantees stability and ease of installation.

Construction and application

This disconnect switch, manufactured by ALPAR, is characterized by a solid three-pole construction with a common frame and drive for all poles. This allows simultaneous disconnection of all phases, which increases the safety of operations. The possibility of using porcelain, composite or silicone insulators allows the disconnect switch to be adapted to specific environmental conditions and operational requirements. It is an ideal solution for both new installations and modernization of existing networks.

Key features and benefits

• Durability and reliability: Construction from high-quality materials ensures long-lasting and trouble-free operation in various weather conditions.
• Versatility: The ability to choose the type of insulators (porcelain, composite, silicone) allows for optimal adaptation to the working environment.
• Safety: Three-pole construction with a common drive guarantees simultaneous disconnection of all phases, minimizing the risk of short circuit or equipment damage.
• Easy installation: The frame construction designed for horizontal mounting facilitates installation and servicing.
• Compliance with standards: The disconnect switch meets the required safety and quality standards, ensuring compliance with applicable regulations.
• Adapted to work in difficult conditions: Designed to operate at temperatures from -40°C to +40°C and air humidity below 100%. Installation at altitudes up to 1000 m above sea level does not affect its operation.

This disconnect switch is particularly recommended for installers due to its simple installation and reliable operation. For end-users, this means long-term and safe operation of the electrical network without fear of failures caused by faulty protection.
