Control cabinet ecoVert® solutions offer cost-effective, flexible and reliable automation solutions in power range from 75kW up to 2700 kW.

In addition to the frequency converter, the cabinet can be supplied with the following:

  • Protection class IP23 or IP54 / IP55
  • Cabinet enclosure Rittal VX25
  • Main isolating switch
  • Semiconductor fuses
  • Mains choke 
  • Mains filter class C3
  • Power connection terminals
  • Heat sink 

Along with other standard fittings such as heating, lighting, top-mounted cable glands etc., Breuer specialize in customized control cabinets. Examples include: metal fittings on the cabinet, colour, special dimensions, sea water resistance, metal frame with increased stiffness, hand rails according to DNV, cooling (reduction or air suction not on the bottom), PLC integration, AFE-power regeneration, protection class up to IP65, etc. A comprehensive protection and diagnostic concept ensures easy installation, and secure operation in rough environments.

Breuer can deliver components as well as total solutions containing switch gear, transformers, frequency converters and motors. Our project engineers will offer you support in component choosing, system design, project design, installation and commissioning.
