Rotary switch 20A, Circuit switch 0-1-2-3, panel mounting front grey black knob SK20-2.8445\P03

Rotary switch – reliable circuit switching

This 20A rotary switch, designed for panel mounting, is a robust solution for controlling electrical circuits. Equipped with a black knob and a gray housing, it offers convenient operation and durability. The design allows switching between 0-1-2-3 positions, making it a versatile element in electrical installations.

Functionality and application

The rotary switch SK20-2.8445\P03 is used in low-voltage electrical installation circuits where frequent switching of currents is required. It will work as a switch, disconnector, switch or control switch. Thanks to the IP65 protection class from the front, it is resistant to dust and water ingress, which increases its reliability in harsh working conditions. Application in closed rooms (degree of pollution 3) and the possibility of operation at temperatures from -40°C to +70°C make it a universal solution for installers and end users.

Key features and benefits

• Versatility: A switch with 0-1-2-3 positions allows for flexible circuit control.
• Durability: Made of plastic, it ensures long-lasting and reliable operation.
• Safety: IP65 protection class guarantees protection against dust and water, minimizing the risk of failure.
• Easy installation: Designed for indirect mounting on the panel, which facilitates installation.
• Suitable for high loads: Rated continuous current of 20A and rated operating power of 4kW (for AC-3, 400V) allow operation of demanding devices.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.
• Wide operating temperature range: The possibility of operation in the temperature range from -40°C to +70°C makes it suitable for industrial applications and in harsh environmental conditions.

Technical parameters in practice

The rated continuous current at 20A means that the switch can safely operate with a load of this value for a long time without overheating. The rated operating power of 4kW at 400V (AC-3) indicates its ability to switch motors and other devices with significant power. Vibration and shock resistance (compliant with IEC standards) confirms its reliability in demanding industrial conditions. The possibility of indirect mounting facilitates integration with various control panel structures.
