DC Brake BR Series (10-600A)

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)
Functions:
  • 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

Typical Applications:
sawing machines
centrifuges
wood working machines
textile machines
conveying systems
