Main (isolating) disconnect switch, 25A, 2-pole HIS-25/2 167347

Main isolating switch – reliable power disconnection

This two-pole main isolating switch with a rated current of 25A is a solid solution for safely disconnecting electrical circuits. It is suitable for both home and commercial installations where reliable operation and high resistance to loads are required. The design allows for easy mounting on a TH35 rail, occupying only 2 modules in width.

Functionality and application

The HIS-25/2 switch is designed to disconnect circuits under AC voltage. Its main task is to provide safe isolation from the power source during maintenance or repair work. The “arrow” symbol on the housing makes it easy to identify the device's function. Thanks to the possibility of locking with a padlock, it can be additionally secured against accidental switching on, which is particularly important in public places or where access to the electrical installation is not restricted.

Key features and benefits

• High switching capacity: A rated switching capacity of 12.5 kA guarantees effective protection of the installation against the effects of short circuits.
• Suitable for larger wires: The terminals allow connection of wires with a cross-section of up to 50mm², providing great flexibility when choosing the appropriate cable.
• Strength and durability: Made of high-quality materials, it ensures long-lasting and trouble-free operation. Short-circuit strength (Icw) is 1 kA.
• Safety of use: The IP40 protection class protects against accidental contact and the ingress of solid objects larger than 1mm.
• Wide voltage range: Suitable for operation at a rated voltage of 415 V and a minimum rated voltage of 240 V, making it a universal solution for various installations.
• Locking option: Protection against accidental switching on with a padlock increases safety during work and use.
• Continuous current: High continuous current up to 125A allows use in circuits with high power consumption.

This switch is not only a safety element, but also a convenient tool for installers – thanks to its compact size and ease of installation, it saves time and space in the switchboard. For the end user, this means above all peace of mind and confidence in the safe operation of the electrical installation.
