Air circuit breakers VA07

Description


VA07 circuit breakers are installed into transformer substations, switch and control gears and main distribution boards as lead-in, sectional and distribution units for connecting and protecting drives, generators, transformers, buses and cables at industrial and residential construction sites, electric supply of high technology manufactures, banks and utilities. They are intended for exploitation in electric units with rated operating voltage limited to 690V per rated current from 800 to 4000A.

These ACB correspond to the requirements of IEC 60947-2.

Advantages


  • High rated breaking capacity ratings up to 100kA.
  • Equal ratings of service and ultimate short-circuit breaking capacity: Ics=Icu.
  • Expanded standard configuration.
  • Maximum saved space inside the distribution board.
  • Equal bay in the panel door independently from the ACB dimensions.
  • Heightened number of power cycles up to 30 000 cycles.
  • Possibility to change main contacts.
  • Fast arc extinguishing owing to Double Break system.
  • Small dissipated power value.
  • Expanded range of selectivity.
  • Raised exploitation safety.
  • Special type option for use in tropical and cold climate conditions as well as corrosive environments.

Design Features


All unit types with rated current limited to 3200A have equal depth (345 mm) and height (460 mm). Panel door bay dimensions are equal for any VA07ACB that facilitate its mounting inside the distribution board.

Using an electronic release ensuring performing the following functions:

- protection from long-term overload;
- short circuit protection;
- adjustable instantaneous trip function.

“Double Break” system guarantees fast short circuit arc-breaking at the expense of dividing it in two with the help of making breaks in two point of every pole. As a result, it provides for lowering the contacts’ wear resistance and erosion. Using two transformers on each pole. The first transformer is linear. It is responsible for current signal control. It ensures high accuracy class within the whole short-circuit currents range. The second transformer is intended for the electronic trip input.
Basic shipment configurations predetermine that main contacts type for units per current up to 3200A is horizontal, up to 4000 – vertical. Front and combined connection are optional. Main contacts can be easily changed to new ones. It provides for extending the ACB service life. Changing each contacts takes no longer than 15 minutes.
