4-pole changeover switch 4G40-10-U with "0" position (0-1) Un: 690 V~ In: 40 A Disconnector 63-840304-041

Universal cam switch for demanding applications

The 4G40-10-U cam switch is a component designed for safe and reliable switching of electrical circuits. Designed by Apator S.A., it combines a proven design with modern materials, ensuring long-lasting and efficient operation in various conditions. The device is particularly useful where manual circuit change is required, as well as in applications where it is important to be able to disconnect the power supply for maintenance or repair.

Construction and application

This three-pole (3P) cam switch with a rated current of 40A is designed for panel mounting. It has a clear "0" position (0-1), which makes it easy to visually identify the circuit status – off or on. The "U" designation means no housing, making it ideal for integration with existing switchboards or control cabinets. Connection of the main contacts is realized by screw connections, which ensures a secure and durable connection of the wires. The rated operating power for AC-3 at 400V is 21 kW, which demonstrates its ability to handle significant loads.

Advantages for installers and end users

• Versatility: Can be used in various installations – industrial, mining, marine and in transformer stations and control cabinets.
• Solid construction: The use of high-quality insulating materials and contacts guarantees reliability and long life of the device.
• Easy installation: Designed for panel mounting, it simplifies integration with existing systems. Screw connections ensure quick and secure wiring.
• Safety: A clear "0" position provides unambiguous information about the circuit status, minimizing the risk of errors during operation and maintenance.
• Switching program: Compliance with scheme No. 10 ensures flexibility in circuit configuration.
• Protection class IP40: Provides protection against access to live parts and against the ingress of solid objects larger than 1mm – important for safe use.

The 4G40-10-U cam switch is a proven component that will find application both in new installations and during the modernization of existing electrical systems. Its solid construction and ease of installation make it an ideal choice for professionals, and the clear "0" position increases safety for all users.
