In the operation and maintenance of electrical equipment, the switch handle, as a key control component, plays a vital role. The Handle Switch φ8*8mm 40*55mm is specially designed for isolating switch fuse groups with rated currents of 63A and 125A, and is suitable for a variety of electrical application scenarios. Its front rotation operation mode, composed of operating mechanism, contact system, handle, etc., and fully enclosed structural design ensures the safety of operators and equipment, and effectively prevents the risk of electric shock and mechanical damage.

Installation conditions

1. Temperature: The ambient air temperature is not higher than +40℃ and not lower than -5℃, ensuring that the equipment operates within a suitable temperature range.

2. Altitude: The altitude of the installation site does not exceed 2000 meters to ensure that the electrical and mechanical properties of the equipment are not affected by the high altitude environment.

3. Humidity: When the maximum temperature is +40℃, the relative humidity of the air does not exceed 50%. At lower temperatures, higher relative humidity can be allowed, such as 90% at 20℃. For condensation occasionally generated by temperature changes, appropriate measures should be taken, such as installing dehumidification equipment or using sealants, to prevent condensation from damaging the equipment.

4. Pollution level: The ambient pollution level is level 3, which is suitable for general industrial environments and some lightly polluted environments.

5. Installation environment: The switch should be installed in a place without significant shaking, impact vibration, and wind and snow invasion, and there should be no gas and dust in the medium that is sufficient to corrode metal and destroy insulation, to ensure the stable operation and electrical insulation performance of the equipment.

Precautions for use

1. Regular inspection: The operating handle should be inspected regularly to ensure that its operation is flexible and reliable. The inspection content includes whether the handle rotates smoothly, whether there is any jamming phenomenon, whether the spring of the operating mechanism is strong, and whether the contact system has good contact.

2. Operation force: During operation, avoid using excessive force to avoid damaging the operating mechanism. The correct operation method is to gently rotate the handle by hand to make the switch open and close smoothly, and avoid excessive force that may cause damage to the mechanism or deformation of the contact.

3. Cleaning and maintenance: Clean the handle and switch surface regularly to prevent dust and dirt from affecting the operating performance. When cleaning, use a clean soft cloth and avoid using corrosive cleaning agents to avoid damaging the surface coating and electrical insulation performance of the handle.

The Handle Switch φ8*8mm 40*55mm plays an important role in electrical equipment. Through its fully enclosed structure and quick operation mechanism, it ensures the reliability and safety of operation. Its unique contact system and the interlocking design of the handle and the cabinet door further improve the operating safety and maintenance convenience of the equipment. Correct installation and use of the switch handle can effectively improve the operating efficiency and safety of electrical equipment and provide strong guarantees for the stable operation of the electrical system. In daily use, operators should strictly operate and maintain in accordance with the installation conditions and precautions to ensure the long-term stable operation of the equipment.
