Application
These Resistors are used in conjuction with appropriate control equipment to accelerate, dynamic braking of motors.

These resistors are also ideally suited for use in the secondary of AC wound rotor motors for accelerating speed regulating services.

These resistors are also used as neutral grounding resistors. AC and DC dynamic braking load banks, current limiting and blast for mercury vapor lamp
