Switch 0-star-triangle CS 40 12 U 004773135

Star-delta switch for motors – reliable starting and control

This four-pole 0-star-delta switch from the CS 40 U series by ETI-POLAM is a key element in electrical installations where efficient and safe starting of three-phase motors is required. It allows smooth switching between star and delta circuits, reducing starting currents and minimizing network load. This is an ideal solution for both professional installers and end-users looking for reliable motor control.

Functionality and application

The CS 40 12 U switch is designed for panel mounting and installation in distribution boards. Its construction based on screw connections ensures solid and durable electrical connections. The actuator in the form of a knob guarantees convenient and precise operation. Thanks to the presence of the "0" position, it is possible to completely disconnect the circuit, which increases safety. The switch finds application in:

• Three-phase motor controllers
• Electrical distribution boards
• Industrial applications
• Automation systems

Key features and benefits

• High resistance to surge currents: Characteristic C allows it to react more slowly to short current spikes, making it well suited for starting devices with a motor.
• Rated AC-3 operating power up to 18.5 kW: Enables control of motors with significant power, making it a versatile solution for various applications.
• Rated continuous current 40 A: Ensures stable operation even under heavy load.
• Solid construction: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Safety of use: The presence of the "0" position and solid screw connections minimize the risk of short circuits and damage.
• Easy installation: Designed for panel mounting, which facilitates integration with existing installations.
• Versatility: Can be used in various industrial and commercial environments.

Remember that proper selection of the switch for a specific application is crucial to ensure safety and system efficiency. If in doubt, we recommend consulting a qualified electrician or engineer.
