Main isolating disconnect switch IS-100/4 276285

Main isolating switch – safety and control in your installation

The IS-100/4 main isolating switch from Eaton is a reliable element of every distribution board, providing safe and controlled disconnection of electrical circuits. The device is designed to operate at AC 400V and a rated current of 100A, making it an ideal solution for both domestic and industrial installations. The 4-pole design guarantees complete isolation, and the high short-circuit strength (up to 12.5kA) provides protection against the effects of overloads and short circuits.

Functionality and installation

The IS-100/4 switch is characterized by a wide range of permissible cross-sections of connection wires – up to 50mm2. This allows you to connect cables of different thicknesses, which increases the flexibility of the installation. Mounting is done on a standard TS35 mm rail, which facilitates integration with existing infrastructure. Additionally, the presence of an “arrow” symbol on the housing makes it easier to identify the function of the device.

Key features and benefits

• High short-circuit strength: The ability to withstand a short circuit of up to 12.5kA provides effective protection of the electrical installation and minimizes the risk of damage.
• Wide range of wire cross-sections: The possibility of connecting wires up to 50mm2 gives great freedom in choosing cables and adapting them to the needs of a specific installation.
• Safety of use: The 4-pole design ensures complete isolation of the circuit after switching off, minimizing the risk of electric shock during service work.
• Durable construction: Made of high-quality materials, the switch ensures long-lasting and reliable operation.
• Easy installation: Standard mounting on a TS35 mm rail facilitates integration with the existing distribution board.
• Contact position indicator: Allows for quick visual verification of the device status – whether it is on or off.
• Protection class IP40: Provides protection against touching solid objects with a diameter greater than 1mm.

Thanks to these features, the IS-100/4 switch is not only a protective element, but also a convenient tool for installers and end-users, ensuring reliable operation and safety in every situation.
