Disconnect switch 20A, Disconnector 0-1 (6-pole), in OB11 housing with lockable front SK20-3.8210\OB11Z

Cam switch – reliable switching in demanding conditions

This six-pole cam switch, enclosed in a robust OB11 housing, is a solid solution for frequent switching of electrical circuits. Designed for both professional and end-user applications, it provides safe and convenient operation. The design with a closable front increases resistance to external factors, and the high IP65 degree of protection guarantees protection against dust and moisture.

Construction and application

The cam switch SK20-3.8210\OB11Z is a device used for manual switching of electrical circuits. Its construction based on a cam mechanism ensures smooth and precise circuit changeover. This model is equipped with a "0" position, which allows for complete disconnection of the load, increasing safety during maintenance or repair. It finds application in motor controllers, power distribution boards, industrial machines and equipment, and in building installations requiring reliable circuit switching.

Key features and benefits

• Durable construction: The housing made of plastic provides resistance to mechanical damage and corrosion.
• High degree of protection (IP65): Protection against dust and water jets makes the switch suitable for harsh environmental conditions.
• Six poles: Allows switching of more circuits simultaneously, increasing the functionality of the device.
• "0" position: Ensures safe disconnection of the load during servicing or repair.
• Screw connection: Guarantees a secure and durable connection of wires.
• Rated continuous current 20A: Allows safe use in installations with appropriate load.
• Rated operating power for AC-3 4kW: Suitable for many industrial and construction applications.
• Cam mechanism: Ensures smooth and precise circuit switching, minimizing the risk of damage.

Mounting and operation

The cam switch SK20-3.8210\OB11Z is designed for indirect mounting using screws (not included in the set). The mounting is simple and intuitive, and the connection of wires is done using screw terminals – just prepare the wires properly and tighten them with a torque of 0.5 Nm. The device is adapted to work in a wide range of ambient temperatures (-40°C to +70°C), which makes it a universal solution for various applications. Remember to follow safety rules when working with electrical devices and to regularly check the technical condition of the switch.
