Star-delta switch disconnector 4G25-12-U Un: 690 V~ In: 25 A 63-840310-031

Cam switch for demanding applications

This 4G25-12-U cam switch, designed to operate at a rated voltage of 690 V~ and a current of 25 A, is a robust solution for switching star-delta circuits. It is indispensable in applications requiring reliable and safe control of motors and other electrical devices. The construction based on proven solutions from the 4G series guarantees high durability and resistance to industrial conditions.

Construction and application

Cam switches of the 4G series are low-voltage devices designed for a wide range of applications – from transformer stations, through control cabinets, to switchgear in industry, mining and shipbuilding. They utilize high-quality insulating and contact materials, which translates into long life and trouble-free operation. This particular model, with position 0 and screw connection of the main contacts, is ideal as a star-delta switch, allowing optimal matching of engine operating parameters. Thanks to its compact size, it can be easily integrated with existing infrastructure.

Key features and benefits

• Versatility: Can be used in various configurations – as a motor switch, star-delta switch or in auxiliary circuits.
• Durability: Built from high-quality materials, resistant to overloads and dynamic short-circuit currents (when protected by fuses).
• Reliability: Proven design solutions ensure long-term and trouble-free operation.
• Easy installation: Designed for indirect mounting, which facilitates integration with various types of enclosures and switchgear.
• Safety: Protection class IP40 provides protection against accidental contact.
• Rated operating power AC-3: 13 kW at 400 V – sufficient for many industrial applications.
• Intuitive operation: The actuator in the form of a knob provides precise and convenient control.

It has four poles, the rated continuous current is 25 A and the rated operating power AC-3 at 400 V is 13 kW. Protection class IP40 protects against accidental contact.

This cam switch is an investment in reliable and efficient electrical energy control in your installation.
