3 Phase Brake Switch with Short Circuit Brake in a Steel 3 Gang Box for use with AC or DC output wind 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. 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. Assembled in the USA using Global Materials. 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 Documents: Instructions & Wiring Diagram
