Reversing starter 20A, direction of rotation changeover switch L-0-P, in OB12 enclosure. SK20-3.8368\OB12

Universal changeover switch for reversing the direction of rotation

This three-pole changeover switch with a rated current of 20A is a reliable solution for controlling motors and other electrical devices. Designed for frequent switching, it allows you to change the direction of rotation or select different circuits. Model SK20-3.8368\OB12 comes with a robust OB12 enclosure, providing protection against external factors.

Construction and application

The changeover switch with a 0 position (L-0-P) allows for safe switching on, off and reversing the direction of motor rotation. The design with a knob ensures convenient and intuitive operation. Thanks to screw connections, installation is quick and easy. It will work both in industrial installations and in workshops or homes, wherever it is necessary to change the direction of the motor rotation or switch between different circuits.

Key features and benefits

• Durable construction: The housing made of plastic provides resistance to mechanical damage and corrosion.
• High resistance to external conditions: IP65 protection rating guarantees protection against dust and water jets – ideal for use in harsh conditions.
• Safe use: The 0 position allows for complete disconnection of the circuit during maintenance or repair.
• Versatility: Possibility of mounting on a panel or in a distribution box (although not designed for it).
• Suitable for high loads: The rated power for AC-3 is 4 kW at 400V, allowing control of most standard motors.
• Durable operation: Mechanical endurance of 3 million switching cycles guarantees long device life.
• Wide operating temperature range: The device retains its properties in the temperature range from -40°C to +70°C.
• Compliance with standards: Meets safety requirements, confirmed by certificates (CE, RU, UA).

Operating parameters

The continuous rated current is 20A, and the conventional short-circuit current is 10kA – these parameters ensure safe operation of the device in typical applications. The cross-section of the connection cables is 1...4 mm², which makes it easy to adapt to the existing electrical installation. The tightening torque of the terminals is 0.5 Nm – it should be observed during installation to ensure a correct electrical connection.
