Braking Wire Wound Resistors

Features and Applications
3000W to 10800W (on chassis) metal clad wire wound braking resistors, small sized.
Excluded aluminum housing provides strong mechanical structure. Minimum resistance value of 0.4
ohm and up to 3500V AC insulating voltage. Metal tab terminals and wire leaded terminals areavailable. Thermostat and terminal box are optional.
Application includes sliding rate resistor, braking resistor and harmonic filter resistor of the windmill
generator and power electronics.
