Cam switch 40A, Three-phase reversing starter switch, in OB14 enclosure. SK40-5.8538\OB14

Rotary disconnect switches – reliable circuit control

This three-pole rotary disconnect switch with a rated current of 40A is a solid solution for manually switching electrical circuits on and off. It will work in both simple installations and more demanding industrial applications. The design in an OB14 housing provides protection against external conditions, and the ability to change the direction of rotation expands its range of applications.

Design and operating parameters

The switch is designed for durability and safety. Made of durable plastic, it is characterized by a high degree of protection IP65 on the front side, which guarantees resistance to dust and moisture. The connection of the main contacts is made using screw connections, ensuring a secure and stable connection of the wires. Designed to operate at temperatures from -40°C to +70°C, it is resistant to extreme environmental conditions.

Application and benefits

This model of rotary disconnect switch is particularly useful in applications requiring frequent switching of circuits, such as:

• Electric motor control – thanks to the ability to change the direction of rotation, ideal for drives requiring precise control.
• Disconnecting circuits for maintenance or repair work.
• Applications in mechanical industry where reliability and durability are required.
• Installations requiring manual control of electrical devices.

The rated operating power for AC-3 is 12 kW, making it suitable for a wide range of applications. The lack of normally open and normally closed auxiliary contacts simplifies installation and configuration. The "0" position allows for safe disconnection of the circuit, and the inability to return to the "0" position ensures confidence in maintaining the off state. Complete device execution in OB14 housing facilitates mounting and ensures immediate readiness for use.
