Main (isolating) switch, 25A, 1-pole HIS-25/1 167346

Main isolating switch – safety and control in your installation

This single-pole isolating switch HIS-25/1 from Eaton is a reliable device for safely disconnecting electrical circuits. It finds application in both home and industrial installations, providing effective protection against overload and short circuit. Its compact size (1 module width) allows for easy mounting in switchboards.

Functionality and technical parameters

The device is designed to operate with AC 240V and a rated current of 25A. The rated switching capacity of 12.5 kA guarantees effective circuit interruption in the event of a failure. The IP40 protection class protects against the ingress of solid objects larger than 1mm, making it suitable for most indoor environments. The short-circuit strength (Icw) is 1 kA, which confirms its solidity and reliability.

Additionally, the switch allows for safe locking with a padlock, preventing accidental switching on or off by unauthorized persons. The terminals allow connection of cables with a cross-section of up to 50mm², and the high continuous current of up to 125A provides a power reserve for future needs. The “arrow” symbol on the housing makes it easier to identify the function of the device.
