Braking Devices AC-BR 230-10 ... 600, AC-BR 400-10 ... 600

Function:

  • DC braking
  • control via motor contactor
  • 2 separately adjustable parameters braking current, braking time
  • potential-free output for motor contactor interlocking during braking - loadable with 250V/8A
  • potential-free output for braking contactor (devices from 40A on) - loadable with 250V/8A

Features:

  • DC braking with one-way rectification
  • suitable for all asynchronous motors
  • easy mounting, also for retrofitting into existing plants
  • wear-resistant and maintenance-free
  • special voltages up to 600V (20A-devices)
  • special voltages up to 690V (devices from 40A on)
  • integrated braking contactor (devices up to 20A)
  • for snap-mounting onto 35mm top-hat-rail (devices up to 20A)
  • degree of protection IP 20 (BR 230/400 - 10 ... 20)
    degree of protection IP 00 (BR 230/400 - 40 ... 600)

Typical Applications:

  • sawing machines
  • centrifuges
  • wood working machines
  • textile machines
  • conveying systems
