Main isolating disconnect switch IS-40/3 276272

Main isolating switch – reliable power disconnection

The IS-40/3 switch is a robust and reliable device designed for the safe disconnection of electrical circuits. Designed by Eaton, it meets the requirements of IEC/EN 60947-3 standards, guaranteeing high quality and safety of use. It is a key element of any electrical installation, providing effective isolation and protection during maintenance or repair.

Functionality and application

This three-pole (3P) switch with a rated current of 40A is perfect for installations with a voltage of 415V. Its design allows for easy and reliable disconnection of power, which is particularly important during service or modernization work. The wide range of connection terminals, up to 50mm², allows connection of cables of various thicknesses, increasing the flexibility of the installation. Short-circuit strength at 12.5kA provides protection against the effects of overloads and short circuits. Additionally, the "arrow" symbol on the housing facilitates visual identification of the switch status – on or off.

Advantages for professionals and end users

• High contact durability: Ensures long-term and trouble-free operation, even with frequent switching.
• Wide range of wires: The ability to connect wires up to 50mm² simplifies installation and adaptation to different installations.
