MAK-ru current transformers stand out from their analogues
Reliability and safety
Transformers are manufactured as non-disassembled and sealed, which excludes access to the secondary winding.
The housing is made of glass-filled polyamide (self-extinguishing material) providing high strength in a wide temperature range as well as the highest dielectric parameters.
Modern packaging protects against any damage during transportation.
Each transformer has a QR code that provides quick access to all its specifications, production and verification dates, testing results.
Service life - 25 years.
Ease of installation and fixing
Suitable even for very limited spaces thanks to small dimensions.
Can be securely fastened to busbar or cable of various cross sections and configurations, mounting plate and DIN rail; full set of fasteners is included in the delivery.
Saves internal space in the cabinet: the dimensions enable to perform busbar wiring to circuit breakers without the use of expansion poles.
The transformer housing has a textured surface, which reduces the chance of slipping and falling during installation.
