Aluminium Housed Wire Wound Braking Resistors
For higher ratings, we can supply 2 or more DBRS in parallel to achieve the required power and resistance (ohmic) value.
General Features
  • These elements have a high overload capacity and cool rapidly
  • Compact construction & Low Noise Level
  • Higher continuous dissipation by mounting directly onto heat sink or cooling surface


  • Nickel Copper Plated M.S. Terminals or 300-500mm long Temperature Resistance Cable
  • Mounting Positions :

  • Any mounting position is possible at full load, but recommended positions are as follows:
  • Installation

  • The resistors do not have a separate safety earth terminal.
  • They must be mounted on a metallic bare, grounded surface or an earth terminal must be affixed to one of the fastening screws
  • Safety

  • For unprotected installation within normal arm’s reach, use a protection against unintended contact
  • Sufficient cooling air must be available and sufficient headroom above the unit for the exiting hot air.

The load must be reduced at higher ambient temperatures
