Rotary disconnect switch 20 A, switch 0-1 (4-pole), panel mount front grey knob black SK20G-2.8210\P03

Robust cam switch for industrial and domestic applications

This four-pole cam switch SK20G-2.8210\P03 is a reliable solution for frequent switching of electrical circuits. Designed for use in demanding industrial environments as well as in home installations, it provides safe and convenient power control. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

Functionality and application

The SK20G cam switch is a device used for manual switching of electrical circuits on and off. Its cam mechanism-based design ensures reliable and precise switching. This model, with a 0-1 disconnector, allows you to choose between two positions – on and off. It is ideal for controlling lighting, electric motors, heating devices and other energy consumers. Front panel mounting simplifies integration with existing installations.

Key features and benefits

• High mechanical resistance: Durable construction allows for a large number of switching cycles – up to 3 million – which translates to a long service life.
• Suitable for high loads: Rated continuous current of 20 A enables safe power supply to most standard electrical devices.
• Wide voltage range: The ability to operate at an insulation voltage of up to 690 V makes the switch universal and can be used in various installations.
• Safety of use: Meets the required safety standards (see Compliance with standards section), providing protection against electric shock and equipment damage.
• Easy installation: Design adapted for front panel mounting (31/□36 hole) simplifies and speeds up installation.
• Wide operating temperature range: From -40°C to +70°C ensures reliable operation even in difficult environmental conditions.
• High protection against external factors: IP65 protection rating guarantees resistance to dust and water jets, which is particularly important in humid or dusty environments.

Technical parameters in practice

Rated continuous current of 20A means that the switch will safely handle most standard loads in residential and industrial buildings. The four-pole design allows simultaneous switching of all phases and neutral, which is important when powering three-phase devices with higher power. The rated switching power of AC-23A of 3.5 kW (230 V), 6 kW (400 V), 7.5 kW (500 V) and 10 kW (690 V) demonstrates its capabilities in controlling various types of electrical energy consumers. The conventional short-circuit current of 10kA provides protection for the installation in the event of a short circuit.
