Cam switch 20A, Three-phase starter switch (0,Y,A), panel mounting front grey knob black SK20-4.831\P23

Cam switch – reliable switching in your installation

This three-pole cam switch with a rated current of 20A is a solid solution for switching electrical circuits. Designed for both panel mounting and indirect mounting, it can be used in a wide range of installations – from industrial to commercial. The rotary knob design provides convenient and intuitive operation, and high resistance to external factors guarantees long-lasting and trouble-free operation.

Functionality and application

The SK20-4.831\P23 switch is a switching device that allows you to choose from three positions (0-Y-∆), making it ideal for starting three-phase motors or other applications requiring a change in circuit configuration. Made of durable plastic, it provides good insulation and safety. The IP65 protection class guarantees resistance to dust and water ingress, allowing operation in harsh environmental conditions. The possibility of indirect mounting increases installation flexibility.

Key features and benefits

• Versatility: The 0-Y-∆ switch will work in various applications, especially when starting three-phase motors.
• Durability: The housing made of high-quality plastic ensures durability and resistance to mechanical damage.
• Safety: The IP65 protection class protects against the effects of dust and moisture, minimizing the risk of failure and ensuring safe operation.
• Convenient operation: The knob makes it easy to quickly and precisely switch circuits.
• Installation flexibility: The possibility of panel or indirect mounting allows you to adapt the switch to the specifics of the installation.
• Suitable for continuous operation: The rated continuous current of 20A and the rated operating power of 4kW (at 400V) allow for intensive use without the risk of overload.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.

Technical parameters in practice

The rated operating power of 4 kW at a voltage of 400 V means that the switch is able to handle devices with significant power, which is important in industrial applications. The rated continuous current of 20 A ensures stable operation even under heavy load. The three-pole design allows switching all phases in a three-phase circuit, and the lack of auxiliary contacts simplifies the installation diagram in applications where they are not required. Vibration and shock resistance (compliant with IEC standards) guarantees reliability even in harsh industrial conditions.
