40A reversing switch, direction of rotation changeover switch L-0-P, in OB13 enclosure. SK40-3.8368\OB13

Rotary cam switch for changing the direction of rotation – reliability and versatility

This SK40 rotary cam switch, combined with the OB13 housing, is a solid solution for controlling electric motors. Designed for frequent load switching, it ensures safe and efficient operation of the installation. The design allows you to change the direction of the motor's rotation (L-0-P), which is particularly useful in applications requiring precise motion control.

Construction and application

The SK40 rotary cam switch is a complete device, ready for mounting in the OB13 housing. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The switch with a knob allows for intuitive operation and quick switching between different operating modes. It finds application in controlling electric motors in industrial machines and equipment, automation systems, and building installations. Thanks to its high degree of protection IP65, it is resistant to dust and water ingress, allowing its use even in harsh environmental conditions.

Key features and benefits

• High reliability: Rated continuous current of 40A and short-circuit current of 10kA guarantee stable operation even under heavy loads.
• Versatility: The ability to change the direction of rotation (L-0-P) expands the range of applications.
• Safety: IP65 protection rating protects against external factors, minimizing the risk of failure and electric shock.
• Durability: Made of high-quality materials ensures a long service life – confirmed by as many as 3 million switching cycles.
• Easy installation: Complete device in OB13 housing simplifies installation and saves time.
• Resistance to external conditions: Wide operating temperature range (-40°C to +70°C) allows operation in demanding industrial conditions.
• Protection against accidental contact: The housing provides additional safety of use.
• Adapted to different wire cross-sections: Support for wires with a cross-section from 4 to 10 mm² provides flexibility when connecting to the installation.

Technical parameters in practice

The rated power for AC-3 is 12 kW at 400V – this means that the switch will easily handle motors of this power. The housing material made of plastic provides good electrical insulation and corrosion resistance. The lack of auxiliary contacts makes the device simpler to operate and more reliable – it focuses on the basic function of switching the load. Screw connection of the main contacts guarantees a secure and durable connection of the power supply cables.
