Brake resistors for SINAMICS G100D

SINAMICS G110D - Brake Resistors

Decentral drive technology requires special solutions. The inverters must be adapted to the prevailing environmental conditions and must reliably fulfil their tasks. KOCH offers fitting brake resistors with a high protection class. KOCH is also capable of meeting specific requirements at any time. The solution shown here has a wave hose, which was needed as insect protection for an airport project. KOCH offers many other customer-specific solutions.

***at an ambient temperature of 20° C

  • compact
  • protection class up to IP 65*
  • highly impulse secure
  • low inductance
  • "intrinsically safe"** under persistent overloads
    • no fault to frame
    • no short-circuit
    • self-extinguishing

*Test conditions: Water jet from nozzle with an inner diameter of 6.3mm, volume flow 12.5l/min +/- 5%, water pressure in accordance with the volume flow, distance 2.5-3m, test duration 3min

**the intrinsically safety is usually given with 4 time of permanent type power
