Resistors And  
Resistive Applications  
Mini Braking High Power Resistor Assemblies [Preliminary]  
The MBVA series of high power metal-clad wire wound resistors are designed for industrial high  
power applications & dump resistor for wind turbine.The powerful components comprise two,  
three or four high power resistors housed in partial steel covers at each end. These models are  
specially constructed for overload pulses. They have a thermostat and terminal box as optional.  
The most common applications for these models are: motor drives, braking and snubber applications  
And power sources for industrial equipment.
