Air Circuit breakers

Modern technology

Air circuit breakers are used as the first protection after the transformer because they have a high rated current. Widely used in power plants, factories, mining plants, intelligent buildings and in renewable energy sources.

Product quality is guaranteed by the Rhenes inspection and quality department. In addition, air circuit breakers from each batch are selectively checked at Avitron Polska.

Functions:

  • Protection of electrical installation against short circuit,
  • Undervoltage protection
  • Overload protection,
  • Protection against other dangerous hazards for the installation.
