Cam switch disconnector 20A, switch 0-1 (1 - pole), in OB11 enclosure. SK20-1.825\OB11

Cam switch – reliable circuit control

This 20A cam switch, combined with the OB11 housing, is a solid solution for frequent switching of electrical circuits. Designed for both professional and home use, it provides safe and convenient operation. The design with a 0 position allows for complete disconnection of the circuit, which increases safety during maintenance or repair.

Construction and application

The cam switch SK20-1.825\OB11 is a device used for manual switching of electrical circuits. Its main advantage is the ability to switch frequently without the risk of damage, making it an ideal choice for controlling lighting, small electric motors (up to 4 kW at 400V) and other devices requiring frequent switching. Made of durable plastic, it is resistant to mechanical damage and ensures long-term operation. The IP65 protection class guarantees protection against dust and water jets, allowing installation in various environmental conditions.

Key features and benefits

• Durable construction: The housing made of plastic provides resistance to mechanical damage and corrosion.
• Safety of use: It has a 0 position, allowing for complete disconnection of the circuit during servicing or maintenance.
• High resistance to external conditions: IP65 protection class protects against dust and water jets, allowing installation in difficult conditions.
• Adapted for frequent switching: The switch design allows for a large number of switching cycles (3 million), making it ideal for applications requiring frequent control.
• Easy installation: Screw connection of the main contacts simplifies and speeds up installation.
• Versatility: Suitable for controlling various electrical devices with a power of up to 4 kW (at 400V).
• Continuous rated current 20A: Ensures safe operation of the installation with a load of up to 20A.

Technical parameters in practice

The rated power for AC-3 at 400V is 4 kW – this means that this switch can be safely used to control electric motors with a power of up to 4 kW in AC-3 systems (motor starting). The lack of auxiliary contacts makes it a simple solution for basic switching applications. The housing material – plastic – provides lightness and corrosion resistance, and the lack of the possibility of indirect mounting simplifies installation in standard applications. The use of a knob as the actuating element guarantees convenient and precise operation.
