Main (isolating) switch, 25A, 3-pole HIS-25/3 167348

Main (isolating) switch – reliable power disconnection

This 3-pole isolating switch HIS-25/3 from Eaton is a robust solution for safely disconnecting electrical circuits. Designed for both residential and industrial installations, it provides effective isolation and protection against accidental switching on. Its construction allows for easy mounting in distribution boards, and the ability to lock with a padlock further increases the level of security.

Functionality and technical parameters

The HIS-25/3 switch is characterized by a rated current of 25A and a rated voltage of 415V. The rated switching capacity is 12.5 kA, which guarantees effective protection in the event of a short circuit. The IP40 protection class provides basic protection against solid objects, which is important in environments with increased dust. The device occupies 3 modules in width, which facilitates its integration with existing electrical infrastructure. The short-circuit strength (Icw) is 1 kA, and the installation depth is 69.5 mm.

Advantages for installers and users

• Safety: Provides effective circuit isolation, minimizing the risk of electric shock during maintenance or repair.
• Versatility: Can function as both a main and service disconnect switch, increasing its usefulness in various applications.
• Easy installation: Compact dimensions and the possibility of indirect mounting facilitate installation in distribution boards.
• Padlockable: Additional security feature against unauthorized switching on – particularly important in public places or where access to the installation is restricted.
• High wire durability: Terminals allow connection of wires with a cross-section of up to 50mm², ensuring a stable connection even under high loads.
• High continuous current: The ability to operate with a continuous current of up to 125A provides power reserve and reliable operation.
• Clear marking: The “arrow” symbol on the housing makes it easy to identify the function of the device and quickly read the circuit status.
