Construction and application

A cam switch is a device used to manually switch electrical circuits on and off. In this model, thanks to the 0-Y-A (0-Y-Δ) configuration, it is possible to switch between different connection schemes, making it a versatile element of the electrical installation. It finds application in three-phase motor starters, changing the direction of rotation, and in applications requiring precise control of circuits. Made of durable materials, it guarantees long-lasting and trouble-free operation.

Key features and benefits

• High resistance to external factors: IP65 protection class provides effective protection against dust and moisture, enabling operation in harsh environmental conditions.
• Durable construction: The housing made of plastic is resistant to mechanical damage and ensures safe use.
• Versatile application: The 0-Y-A configuration allows for flexible adaptation to different installation needs.
• Safe connections: Screw connection of the main contacts guarantees a secure and durable connection of the wires.
• Rated operating power: Rated operating power for AC-3 at 400V is 8 kW, which allows for servicing devices with significant power.
• Adapted to work in difficult conditions: The ability to work at temperatures from -40°C to +70°C makes it suitable for outdoor and industrial applications.
• Segmented construction: Allows for creating individual connection programs tailored to specific user needs.
• Simple installation: The switch design facilitates its installation and integration with existing electrical infrastructure.

Technical parameters in practice

Rated continuous current at 16A and high short-circuit resistance (conventional short-circuit current 13 kA) ensure safe and reliable operation of the device even in the event of overloads or short circuits in the network. Mechanical endurance of 3 million switching cycles guarantees a long service life of the switch, even with intensive use. The housing material – plastic – provides electrical insulation and corrosion resistance.
