Cam switch 20A, Switch 1-0-2 (2-pole), base rail mounting front grey knob black SK20-2.8338\BS23

Rotary switch – reliable switching in installations

This 2-pole rotary switch SK20 BS, designed for mounting on a DIN rail, is a solid solution for frequent circuit switching. It is characterized by high mechanical and electrical resistance, making it an ideal choice for both professional installers and end users. Made of high-quality plastic, it ensures durability and safety of use. The black knob makes operation easier and allows for precise circuit control.

Functionality and application

The rotary switch SK20 BS is a device used for manual switching of electrical circuits. Its 1-0-2 design allows you to choose between two different circuits or turn them off (position 0). It will work in applications requiring frequent switching of loads, such as controlling lighting, electric motors or heating devices. Thanks to the IP65 protection class, it is resistant to dust and water ingress, allowing it to be used in harsh environmental conditions.

Key features and benefits

• Durable construction: The housing made of plastic provides resistance to mechanical damage and corrosion.
• High resistance to atmospheric conditions: IP65 protection class guarantees safe use in humid and dusty environments.
• Easy installation: Designed for mounting on a DIN rail, which facilitates and speeds up installation.
• Clear 0 position: A clearly marked 0 position ensures safe circuit disconnection.
• Rated continuous current 20A: Allows connection of devices with significant power consumption.
• Rated operating power for AC-3: 4 kW: Enables control of various electrical receivers.
• Safety of use: Compliance with standards ensures protection against overload and short circuit.
• Wide operating temperature range: From -40°C to +70°C allows use in various climatic conditions.

Technical parameters in practice

The rated continuous current of 20A means that the switch can safely operate with loads drawing this current for a long time. The rated operating power for AC-3 of 4kW indicates its ability to control electric motors with this power. The IP65 protection class is a guarantee of protection against dust and a stream of water, which is particularly important in humid rooms or outdoors. The housing material – plastic – provides lightness and electrical insulation. The possibility of indirect mounting increases the flexibility of the installation, allowing the switch to be adapted to different switchboard configurations.
