Main disconnect switch (isolator), 100A, 1-pole HIS-100/1 142828

Main (isolating) switch 100A – reliable power disconnection

This single-pole main switch, also known as an isolating switch, from Eaton (model HIS-100/1) is a key element of any electrical installation. It is used to safely disconnect the electrical circuit, providing complete isolation from the voltage. This is particularly important during maintenance, repair work and in emergency situations. The device is designed for mounting on a TH-35 rail and is characterized by its compact dimensions – it occupies only one module width.

Functionality and safety in one

The HIS-100/1 switch is designed for durability and reliability. Its rated current is 100A, and the short-circuit strength is 2kA. It provides effective protection against overload and short circuit, and the IP40 protection class guarantees protection against the ingress of solid objects with a diameter of more than 1mm. Additionally, the possibility of locking with a padlock increases the safety of use, preventing accidental switching on of the device during work. The terminals allow connection of wires with a cross-section of up to 50mm², which provides great flexibility when selecting wires for the installation. High continuous current up to 125A provides power reserve and stable operation even under heavy load.

Key features and applications

• Purpose: Safe disconnection of electrical circuits in building and industrial installations.
• Mounting: Easy mounting on TH-35 rail – a standard solution in most switchboards.
• Durability: Rated switching capacity of 10 kA ensures resistance to high short-circuit currents.
• Safety: The possibility of locking with a padlock protects against accidental switching on during service work.
• Compatibility: Designed to work with AC 240V voltage.
• Markings: Equipped with a clear "arrow" symbol to facilitate identification of the device's function.
• Application: Ideal as a main switch in electrical switchboards, providing safe disconnection of the entire circuit or part of it.
• Wire cross-section: Support for wires with a cross-section of up to 50mm² gives great freedom in choosing the appropriate cables for a specific application.

This switch is a solid and reliable solution for both professional installers and end-users looking for a safe way to disconnect power in their electrical installation.
