Cam switch 20A, 1-0-2 switch (3-pole), in OB12 enclosure. SK20-3.8380\OB12

Universal cam switch – reliable switching in your installation

This three-pole cam switch, with a rated current of 20A, is a solid solution for controlling electrical circuits. The design with a 0 position (disconnect) and a high degree of protection IP65 make it an ideal element for both indoor and industrial environments. Made of durable plastic, it provides durability and resistance to mechanical damage. The switch comes with an OB12 housing, which simplifies installation and provides additional protection.

Functionality and application

The cam switch SK20-3.8380\OB12 is used for manual switching of electrical circuits. Its design allows you to choose between three positions – 0 (off), 1 and 2 – making it a versatile tool in many applications. It will be perfect for:

• Control panels: as an element enabling the change of power circuits.
• Machines and equipment: for selecting the operating mode or disconnecting the power supply during maintenance.
• Lighting installations: for switching groups of receivers.
• Industrial applications: where reliability and resistance to environmental conditions are required.

Thanks to screw connections, installation is simple and intuitive, and the ability to connect cables with a cross-section of 1…4 mm² provides flexibility in choosing the appropriate cables.

Design features and operating parameters

The switch has been designed with safety and durability in mind. The degree of protection IP65 guarantees protection against water jets and against touching live parts inside the housing – which is particularly important in humid or dusty environments. Mechanical endurance of 3 million switching cycles testifies to the long service life of the device. In addition, the switch meets safety standards, ensuring reliable operation even in difficult working conditions (ambient temperature from -40°C to +70°C). The rated operating power for AC-3 is 4 kW at 400V, which allows you to operate various electrical receivers. The short-circuit withstand current Icw(1s) is 0.25 kA and the making current Icm is 0.34 kA.
