ARMAT molded case circuit breakers are used in various types of low-voltage switchgear – from distribution boards to MCCB 1600 A. They are part of integrated solutions based on ARMAT IEK products for creating power distribution systems for buildings and structures, including industrial and high-tech facilities.
Due to high breaking capacity (up to 150 kA), the ARMAT molded case circuit breaker line is ideal for use in energy-intensive industrial facilities. In combination with ARMAT air circuit breakers, they are used in MCCB up to 6300 A.
The entire ARMAT power circuit breaker line (air and molded case) is manufactured on modern, fully automated equipment with constant quality control.
IEK electrical products are thoroughly tested both in independent laboratories and in the IEK GROUP's own laboratory in Moscow.
We are confident in the high quality and reliability of the ARMAT line power breakers – that is why their service warranty period is 5 years!
