Main isolating disconnect switch IS-100/2 276283

Isolator switch – safety and reliability in installation

The IS-100/2 main isolating switch is a reliable device designed for safely disconnecting electrical circuits. Its two-pole (2P) design and rated current of 100A make it an ideal solution for both home and commercial installations. It provides effective insulation and control over the flow of current, which is crucial for the safety of use and maintenance of the electrical installation.

Functionality and application

The device is designed to operate at AC 415V, and its width of 2 modules allows for easy mounting in standard distribution boards. Equipped with a clear “arrow” symbol on the housing, it facilitates visual identification of the on/off status. The IP40 protection class guarantees protection against contact with foreign objects with a diameter of more than 1mm, which increases safety. Thanks to its high short-circuit strength (Icw 2kA and rated switching capacity of 10kA), the switch effectively protects the installation from the effects of overloads and short circuits.

Key features and benefits

• High short-circuit strength: The ability to withstand a short circuit of up to 2kA and 10kA ensures protection of the installation in the event of a failure.
• Wide range of conductors: The ability to connect conductors with a cross-section of up to 50mm2 simplifies installation and provides flexibility in cable selection.
• Contact position indicator: Allows for unambiguous visual control of the device status – whether the contacts are open or closed.
• Positive break operation: Ensures reliable and fast switching of circuits.
• Durable contacts: High contact wear resistance guarantees long device life and minimizes the risk of failure due to wear.
• Compact dimensions: A width of 2 modules makes it easy to install in a limited space in the distribution board.
• Safety: IP40 protection class protects against accidental contact with conductive elements.
