Air disconnect switch ONM III SA 24/4 – a reliable solution for medium voltage installations

The ONM III SA 24/4 air disconnect switch is a component designed for the safe and effective mounting of brackets to street lighting fixtures on spun concrete poles. It is particularly recommended for mounting long or multi-arm brackets, where stability and strength are crucial. The switch's design provides a solid connection, minimizing the risk of damage caused by wind or other external factors.

Construction and materials

The switch brackets are made of S235 steel, guaranteeing high mechanical strength and corrosion resistance. Additionally, hot-dip galvanizing provides effective protection against the effects of atmospheric conditions, extending the device's lifespan. This combination of materials and technology makes the switch ideal for operation in harsh environmental conditions.

Application and compatibility

The ONM III SA 24/4 disconnect switch is part of a wide range of ALPAR devices dedicated to the construction and modernization of medium voltage power networks. Its modular design allows for flexible adaptation to different pole and bracket configurations. It is important to note that when mounting a modular disconnect switch intended for a spun concrete pole leg, it is essential to provide the pole's top diameter. This ensures optimal fit and structural stability.

• Bracket mounting: Ideal for mounting both single and multi-arm street lighting fixture brackets.
• Spun concrete poles: Specifically designed for use with spun concrete poles, providing a safe and stable connection.
• Flexibility: Modular design allows adaptation to various installation configurations.
• Strength: S235 steel and hot-dip galvanizing guarantee long-term operation even in harsh weather conditions.
• Compatibility: Possibility of use with various types of insulators (porcelain, composite or silicone) depending on customer needs.
