Air vent valve ONp III SA 24/4 03-033

Air disconnect switch – a reliable safeguard for power lines

The ONp III SA 24/4 air disconnect switch is a key element of power infrastructure, designed for safely disconnecting wires and cables in the open air. The construction of this device, based on solid materials and a well-thought-out design, guarantees long-lasting and trouble-free operation in various weather conditions. It is an ideal solution for both professional installers and end-users who require reliable installation protection.

Construction and application

The ONp III SA 24/4 is characterized by a three-pole design with a common base and drive for all poles. Each pole is based on two supporting insulators – one attached to the base and the other to the bearing movable beam. This construction ensures simultaneous closing and opening of all poles, which increases safety and operation efficiency. The device is made of black-colored, UV-resistant polyamide and hot-dip galvanized steel S235, which ensures durability and corrosion resistance.

This model of disconnect switch is designed for direct mounting on the pole bracket, which simplifies the installation process. The possibility of using different types of insulators – porcelain, composite or silicone – allows adaptation of the device to specific project requirements. The "S" version in the product designation indicates the use of silicone insulators, which offer higher resistance to weather conditions and pollution.

Advantages and benefits

• Durable construction: the combination of UV-resistant polyamide and hot-dip galvanized steel ensures the longevity of the device even in harsh environmental conditions.
• Pole synchronization: the common drive guarantees simultaneous closing and opening of all poles, minimizing the risk of errors and increasing safety.
• Versatility: the ability to choose insulators (porcelain, composite or silicone) allows you to adapt the disconnect switch to specific installation needs.
• Simple installation: the design adapted for direct mounting on the pole bracket facilitates and speeds up the installation process.
• Reliability: solid construction and precise workmanship ensure trouble-free operation for a long time.
• Safety: effectively disconnects the electrical circuit in emergency situations or during maintenance work.
• Resistance to weather conditions: the materials used in production are resistant to UV radiation, moisture and changing temperatures.

Thanks to these features, the ONp III SA 24/4 disconnect switch is a reliable solution for a wide range of applications in power networks.
