Cam switch 40A, 1-0-2 switch (4-pole), for modular installation SK40-4.8396\S10

Cam switches – reliable switching in your installation

The SK40 cam switch, with a rated current of 40A, is a solid solution for building switchboards and controls. Designed for modular installation, it enables convenient and safe circuit switching. The 1-0-2 design (i.e., disconnector) allows you to choose between two power sources or disconnect the load. This four-pole switch will find application in both industrial installations and public buildings.

Construction and application

The SK40 cam switch is a modular element, which means it can be easily mounted in standard switchboard enclosures. The mounting method with four self-tapping screws ensures stability and safety of use. The 1-0-2 design allows for flexible circuit control – from selecting a power source to complete disconnection. This makes the device suitable for applications requiring reliable switching, such as emergency power systems or switching loads between different energy sources.

Key features and benefits

• High reliability: Made of high-quality materials, the switch ensures long-lasting and trouble-free operation.
• Versatility: The ability to mount in standard modular enclosures simplifies integration with existing installations.
• Safety: The 1-0-2 design and high rated current guarantee safe operation even under high loads.
• Flexibility: The ability to choose between two power sources or disconnect the load increases system functionality.
• Durability: Designed for frequent switching - withstands up to 3 million switching cycles.
• Resistance to external conditions: The degree of protection IP65 (depending on the front used) protects against dust and moisture.

The rated continuous current (Iu) is 40A, and the rated insulation voltage (Ue) is 690V. The conventional short-circuit current rating is 10kA, and the permissible cross-section of connection cables is 1...4 mm². The degree of protection depends on the front used and can be IP65.

The SK40 cam switch is an investment in the safety and reliability of your electrical installation. Its solid construction and flexible application make it the ideal choice for both professional installers and end-users looking for a proven solution for controlling electrical circuits.
