Cam switch 20A, -4.824 in OB11 enclosure. SK20-4.824\OB11

Cam switch – reliable switching in your installation

This cam switch with a rated current of 20A is a solid solution for frequent circuit switching. Made of high-quality plastic and enclosed in a durable OB11 housing, it provides safety and long-lasting operation. It is an ideal element for both professional installers and end-users looking for a reliable solution.

Design and application

The cam switch SK20-4.824\OB11 is a device designed for manual switching of electrical circuits. Its design based on a knob allows for convenient and precise change of the circuit state. The use of the OB11 housing guarantees a high degree of protection (IP65) against dust and moisture, making it suitable for operation in harsh environmental conditions. The 8-pole design allows for operation of more complex installations.

Advantages and operating parameters

This switch stands out with a number of features that translate into its functionality and durability:

• High mechanical resistance: Designed for intensive use – withstands up to 3 million switching cycles.
• Safety: IP65 protection degree protects against environmental influences, minimizing the risk of failure and ensuring safe operation.
• Versatility: Possibility of mounting in various applications thanks to compact dimensions and solid construction.
• Adapted to work in a wide temperature range: Trouble-free operation at temperatures from -40°C to +70°C.
• Rated power for AC-3 (400 V): 4 kW – allows operation of devices with significant power consumption.
• Continuous rated current (Iu): 20 A – ensures stable operation even under heavy load.
• Resistance to external factors: Resistant to vibrations, shocks and cyclic damp heat, as confirmed by numerous tests in accordance with IEC standards.
• Screw connection: Provides a secure and durable connection of wires.

Additionally, the presence of the "0" position allows for complete disconnection of the circuit, increasing safety during maintenance or repair. The lack of auxiliary contacts (normally closed, normally open and changeover) simplifies the design and reduces costs without compromising the basic functionality of the switch. The housing material – plastic – provides lightness and good electrical insulation.
