Main disconnect switch (isolator), 100A, 3-pole HIS-100/3 142830

Main switch – safety and reliability in your installation

This 3-pole isolating switch HIS-100/3 from Eaton is a key element of any electrical installation, providing effective disconnection of the circuit when needed. Designed to operate at AC 415V and a rated current of 100A, it is perfect for both domestic and industrial installations. Its modular design (3 module width) makes it easy to mount in distribution boards.

This switch is characterized by a high breaking capacity of 10kA, which guarantees safe operation even in the event of a short circuit. The IP40 protection class provides protection against contact and the ingress of solid objects larger than 1mm, increasing safety. Short-circuit strength at 2kA further increases its reliability.

Functionality and installation

The switch design allows for easy and quick mounting on a TH35 rail. The terminals allow connection of cables with a cross-section of up to 50mm², providing great flexibility in cable selection. An additional advantage is the possibility of locking with a padlock, which protects against accidental or unauthorized switching on. The "arrow" symbol on the housing makes it easier to identify the function of the switch.

This switch is not only a safety element, but also a convenient tool for the installer. Thanks to the high continuous current of up to 125A, it allows for safe circuit loading without the risk of overload. It is worth noting the lack of enforced separation according to DIN VDE 0113 – this is important information for professionals designing and installing electrical systems.
