Main disconnect switch (isolator), 25A, 4-pole HIS-25/4 167349

Main disconnector – reliable protection for electrical installations

This four-pole Eaton isolation switch with a rated current of 25A is a key element of every safe and functional electrical installation. Designed for use in both residential and commercial buildings, it provides effective protection against overloads and short circuits. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation.

Functionality and technical parameters

The HIS-25/4 disconnector is characterized by its versatility and easy mounting on a standard TH35 rail. A width of 4 modules allows for efficient use of space in the distribution board. The rated voltage of 415V and the short-circuit breaking capacity of 12.5kA ensure safety even in demanding operating conditions. The IP40 degree of protection protects against the ingress of solid objects larger than 1mm, which is important in environments with increased dust.

It is worth noting the possibility of padlock locking – an additional security against unauthorized switching on or off of the device. Large terminals allow connection of cables with a cross-section of up to 50mm², which facilitates installation and ensures a secure connection. In addition, this disconnector can withstand a continuous current of up to 125A, making it an ideal solution for circuits with higher power demand.

Application and benefits

The HIS-25/4 disconnector finds wide application in:

• Main electrical distribution boards: as an element disconnecting the power supply to the entire installation or its fragment.
• Distribution boards: to protect individual circuits against overloads and short circuits.
• Industrial installations: where reliable protection against electrical failures is required.
• Residential buildings: ensuring the safety of residents and RTV/AGD equipment.

The installation of this disconnector is simple and intuitive, which will be appreciated by both professional installers and people independently performing electrical work. The "arrow" symbol on the housing makes it easier to identify the direction of current flow, and the lack of an indicator light minimizes the risk of misinterpreting the device's status. The short-circuit strength at the level of 1kA confirms its reliability in emergency situations.
