Air disconnect switch, modular - horizontal 100A with its own construction for surge arresters SN RNM III SA 24/4/100o 03-767

Air disconnect switch – reliable protection for medium voltage networks

This modular air disconnect switch with a current of 100A is designed for efficient and safe operation in medium voltage networks. Its design, in particular the version with the "o" designation, provides for the installation of surge arresters, which further increases the level of installation protection. This is an ideal solution for both professional installers and end-users looking for a reliable element of energy infrastructure.

Design and application

This disconnect switch belongs to the RNM III SA 24/4/100 series, manufactured by ALPAR. Its modular construction allows for flexible adaptation to different network configurations and mounting conditions. The "o" design is dedicated to mounting surge arresters, which is a significant advantage in areas exposed to voltage impulses. It can be used in transformer stations, overhead switchgear and medium voltage lines. Thanks to the possibility of independently setting the poles in relation to each other (in modular versions), the installation becomes more flexible and adapted to the specifics of a given position.

Advantages and benefits

• High reliability: The design based on proven materials and technologies ensures long-lasting and trouble-free operation.
• Overvoltage protection: The version with a design for surge arresters (designation "o") minimizes the risk of equipment damage caused by sudden voltage increases.
• Installation flexibility: The modular construction allows the disconnect switch to be adapted to different installation conditions.
• Easy maintenance: Accessibility of elements facilitates inspections and possible repairs.
• Compatibility with various insulators: The possibility of using porcelain, composite or silicone insulators (depending on the version) allows for cost optimization and adaptation to specific environmental requirements.
• Solid construction: Ensures stability and safe operation even in harsh weather conditions.
• Suitable for manual or motor mounting: The ability to control with manual drives type NRA(u) or motor drives NEA increases the functionality of the device.

ALPAR disconnect switches are characterized by high quality workmanship and compliance with applicable safety standards, which guarantees safe and efficient operation in every electrical installation.
