Cam switch 40A, Isolator switch 1-0-2 (2-pole), in OB2 enclosure. ŁK40-2.8338\OB2

Cam switch – reliable switching in your installation

This two-pole cam switch with a rated current of 40A is a solid solution for frequent circuit switching. The design with a 0 (off) position provides additional safety and convenience. The OB2 housing made of plastic protects against external factors, and the high degree of protection IP65 guarantees resistance to dust and water. It is ideal for both industrial applications and building installations where reliability and durability are required.

Functionality and application

The cam switch is used to manually switch electrical circuits. This model, designated as a 1-0-2 disconnect switch, allows you to choose between three positions: on (1), off (0) and second position (2). Therefore, it finds application in situations where it is necessary to choose between several power sources or receiver circuits. Example applications include:

• Switching power between a generator and the power grid.
• Selecting a power source for devices requiring different voltages or phases.
• Controlling lighting in home or industrial automation systems.
• Operating machines and equipment requiring frequent changes in direction of rotation or operating mode.

Construction features and operating parameters

Made of high-quality materials, the switch is characterized by durability and resistance to mechanical damage. Screw connection of the main contacts ensures a secure and safe connection of wires with a cross-section of 4-10 mm². The housing made of plastic is lightweight and at the same time resistant to corrosion and damage. The switch is designed to operate in a wide range of ambient temperatures (-40°C to +70°C), making it suitable for use in harsh environmental conditions. The rated operating power for AC-3 is 20 kW at 400 V, which confirms its efficiency and reliability. Additionally, it has a high short-circuit rated current I cw(1s) at 0.85 kA and a rated short-circuit making current I cm equal to 1.5 kA, which ensures protection of the installation in the event of overloads or short circuits. This model has a degree of protection IP65, which means high resistance to the ingress of solids and water jets.
