Write a Review


Includes terminal block for easier connections

Brake Switch & Rectifier Combo Includes:

  • 3 phase 50 amp wind turbine brake switch
  • 90 amp bridge rectifier
  • heavy duty electro-galvanized steel recessed back plate
  • all pre-wired and ready to go with quick connect terminal block!

You may choose this rectifier - brake switch combo (MWBSR_COMBO_12/24) to be used on a 12, 24, or 48 volt wind turbine. There can be a slight increase in system efficiency by using the bigger rectifier.


3 phase brake switch with short circuit brake - Also for use with DC output wind turbines


Simple, yet perfect for small turbine installations, this 3-phase switch uses a specialized switch to provide both disconnect capability as well as braking by shorting out the 3 wires of the stator. Although designed specifically for 3-phase turbines it works equally well for single phase AC turbines as well as DC turbines.


50 amp, 3-phase switch with short circuit brake works with 12 volt to 250 volt systems. Designed for 1500 watt and smaller turbines.

Switch Positions:

  • Up: Turbine is connected to the battery or rectifier (switch is closed).
  • Middle: Turbine is fully disconnected (free spinning).
  • Down: Turbine wires are shorted together (brake is on).

This switch will handle 2500 watts continuously.

Rated at:

  • 10 Amps at 250 Volts
  • 15 Amps at 125 Volts
  • 25 Amps at 60 Volts
  • 40 Amps at 30 Volts
  • and 50 Amps at 15 Volts
