Main isolating disconnect switch IS-80/3 276280

Main isolating switch – reliable power disconnection

The IS-80/3 isolating switch is a key element of any electrical installation, providing safe and reliable disconnection of circuits. Designed to operate at AC 415V and a rated current of 80A, it is perfect for both domestic and industrial installations. Its compact design – occupying only 3 modules on a TH-35 rail – allows for easy installation even in limited space within a distribution board.

Construction and application

This three-pole (3P) switch is designed for complete circuit isolation, which is particularly important during maintenance and repair work. The "IS" designation indicates its function as an isolating switch, guaranteeing a visible break in the circuit on the operator side. The “arrow” symbol on the housing further facilitates identification of the device's function. Short-circuit strength at 2kA and switching capacity of 12.5kA provide effective protection of the installation in the event of overloads or short circuits. The IP40 protection rating protects against the ingress of solid objects larger than 1mm, increasing safety of use.

Advantages and benefits for the installer and user

• High short-circuit strength: The ability to withstand a short circuit of 12.5kA ensures the safety of the installation and minimizes the risk of damage.
• Compact dimensions: A width of 3 modules makes it easy to install in tight distribution boards, saving valuable space.
• Durable construction: Made of high-quality materials, it guarantees long life and reliable operation.
• Visible isolation gap: The isolating switch function ensures complete safety during maintenance and repair work.
• Wide range of connection cables: Allows connection of cables with a cross-section of up to 50mm², increasing installation flexibility.
• Contact position indicator: Allows for quick visual control of the device status – whether it is on or off.
• Safety of use: IP40 protection rating protects against the ingress of solids, increasing work safety with the device.
• Adapted to work in various conditions: Rated voltage of 415V and minimum rated voltage of 240V allow for wide application in various electrical installations.
