Rotary disconnect switch 20A, Disconnector 0-1 (1-pole), panel mounting front grey knob black SK20-1.825\P23

Rotary switch – reliable circuit control

This single-pole rotary switch SK20-1.825\P23 is a solid solution for frequent switching of electrical circuits. Designed for both professional and home use, it combines durability, safety and ease of use. The construction allows for mounting on the front panel, making it an ideal choice for machines, devices and electrical installations requiring easy access and control.

Construction and application

The rotary switch SK20 is a device used for manual switching of electrical circuits on and off. This model is characterized by a clear "0" (off) position, which increases safety. Made of durable plastic, it is resistant to mechanical damage and environmental influences. Thanks to the IP65 protection class, it is resistant to dust and water ingress, allowing it to be used even in harsh industrial conditions. The switch with a black knob provides convenient operation and intuitive identification of the circuit status.

Key features and benefits

• Durable construction: The housing made of high-quality plastic ensures long-term reliability even in demanding working conditions.
• High resistance to external factors: The IP65 protection class guarantees protection against dust and water jets, allowing the switch to be used in various environments.
• Safety of use: A clearly marked "0" position ensures certainty of circuit disconnection, minimizing the risk of accidental activation.
• Easy installation: Designed for front panel mounting with screws, making installation and integration with existing systems easier.
• Adapted to work with various loads: Rated continuous current of 20A and rated power for AC-3 of 4 kW allow controlling various electrical devices.
• Wide range of applications: Ideal for controlling motors, lighting, heaters and other electrical devices in industry, workshops and homes.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.

Technical parameters in practice

Rated continuous current of 20A means that the switch can safely operate with a load of up to 20 amps for a long time without overheating or damage. The rated power for AC-3 of 4 kW indicates its ability to control motors with a power of up to 4 kilowatts. Vibration resistance (2-13 Hz ±1mm / 2-100 Hz ±0.7g) and shock resistance (15g/11ms) confirm its reliability in harsh industrial conditions. The cross-section of connection wires 1…4 mm² ensures compatibility with a wide range of electrical wires.
