Main isolating disconnect switch IS-40/2 276271

Isolator switch – safety and reliability in your installation

This two-pole Eaton IS-40/2 isolator switch is a key element ensuring safe and efficient disconnection of electrical circuits. Designed for both professional installers and end-users, it offers a robust construction and high reliability in demanding working conditions. Its compact dimensions – only 2 module widths – allow for easy integration with existing distribution boards.

Functionality and technical parameters

The IS-40/2 isolator switch is designed for operation in alternating current (AC) circuits with a rated voltage of 415V and a rated current of 40A. The rated switching capacity of 12.5kA guarantees effective protection against the effects of short circuits, and the short-circuit withstand (Icw) of 1kA ensures stable operation even under sudden loads. This makes the device perfect for protecting various receivers, from lighting to electrical appliances.

The design of the isolator switch has been designed for ease of installation and intuitive operation. The “arrow” symbol on the housing makes it easy to identify the status of the device – open or closed. The IP40 degree of protection protects against touch and ingress of solids, which increases safety. The lack of a signaling lamp simplifies the construction and minimizes the risk of failure.

Advantages for the installer and user

• High short-circuit withstand: The ability to withstand short circuits up to 12.5kA ensures the safety of the installation and minimizes the risk of damage.
• Compact dimensions: A width of only 2 modules makes it easy to install in tight distribution boards.
• Robust construction: Guarantee of long-term and trouble-free operation in various environmental conditions.
• Simple installation: Intuitive design makes installation easier and faster.
• Contact durability: High contact durability to abrasion translates to a longer device life and less frequent replacement.
• Wide range of cables: The ability to connect cables with a cross-section of up to 50mm2 provides flexibility when choosing the appropriate cables.
• Contact position indicator: Allows for quick visual control of the device status - whether the circuit is open or closed.

This isolator switch is not only a safety element, but also an investment in the peace of mind and reliability of your electrical installation.
