Main disconnect switch (isolator), 125A, 3-pole HIS-125/3 142834

Main disconnector – reliable power disconnection

This three-pole main disconnector, with a rated current of 125A, is a solid solution for safely disconnecting electrical installations. It is suitable for both new and modernized facilities, providing effective protection against overload and short circuit. The design adapted for busbar mounting allows for easy integration with an existing distribution board.

Functionality and technical parameters

The device is characterized by a high breaking capacity of up to 10kA and a short-circuit strength of up to 2kA, which guarantees its reliability in emergency situations. A width of 3 modules makes it easy to fit into limited spaces in distribution cabinets. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The terminals allow connection of conductors with a cross-section of up to 50mm², which provides great flexibility when selecting power cables. The IP40 protection degree protects against contact with solid foreign objects with a diameter of more than 1mm.

• Thanks to the rated current of 125A, it is possible to safely power devices requiring significant power consumption.
• The three-pole design makes the disconnector ideal for use in three-phase electrical installations.
• High breaking capacity at 10kA ensures effective and fast circuit interruption in the event of a short circuit.
• Terminals allow connection of conductors with a cross-section of up to 50mm², which translates to low connection resistance and minimal energy losses.
• The possibility of securing the disconnector with a padlock provides an additional layer of protection against unauthorized access and manipulation.
• Compact dimensions – only 3 modules wide – allow for efficient use of space in the distribution cabinet.
• The “arrow” symbol placed on the housing facilitates quick identification of the device's function as a main switch.

Installation is simple and intuitive, and the solid construction ensures stability and safety of use for many years. This disconnector is an investment in the safety and reliability of your electrical installation.
