Cam switch 32A, Three-phase starter switch (0,Y,A), base rail mounting front grey knob black SK32-4.831\BS03

Three-phase starter switch – reliable motor control

This three-phase cam switch with a rated current of 32A is a solid solution for controlling electric motors. The design allows switching between 0, Y (star) and Δ (delta) settings, making it an ideal choice for starting asynchronous motors. Rail mounting allows for easy integration with existing electrical infrastructure.

Construction and application

The switch is designed for durability and safety. The housing made of plastic provides good insulation, and the IP65 protection class guarantees resistance to dust and moisture – both on the front and inside the housing. This switch is used in switchboards, control cabinets and for direct motor control. It is used in industry, construction and workshops.

Key features and benefits

• Versatility: The ability to switch between 0-Y-Δ settings allows for flexible adaptation to different motor configurations.
• Durability: A continuous rated current of 32A and high mechanical resistance (3 million switching cycles) ensure long-lasting and reliable operation.
• Safety: IP65 protection class protects against environmental influences, minimizing the risk of failure and ensuring safe operation.
• Easy installation: Rail mounting allows for quick and easy installation without the need for additional tools.
• Solid construction: Made of high-quality plastic, it guarantees resistance to mechanical damage and external factors.
• For AC-3 circuits: The rated switching power in AC-3 category is 10 kW at 400V, making it suitable for controlling medium-power motors.
• No auxiliary contacts: The lack of auxiliary contacts simplifies the design and reduces costs, while meeting the requirements of many standard applications.

Operating parameters and compliance with standards

The switch is designed to operate in a wide range of ambient temperatures (-40°C to +70°C). It meets safety standards, which confirms the high quality of workmanship and reliability of the device. The connection cables should have a cross-section of 4 to 10 mm², and the tightening torque of the terminals is 1.2 Nm. The rated insulation voltage is 690V, and the impulse withstand voltage is 4kV.
