Resistance Box are the heavy duty industrial devices that are used for the controlling of the amount of the current flowing through the cables for the adjusting of the parameters like the speed of motor, movement of the machine arms and other. They are equipped with a series of large number of low high value current reducing elements that can be easily connected to the circuit with the help of plug-ins to select different values very easily. Resistance Box are designed as per the electrical standards which make them capable to resist high powdered flow and are also provided with a protection unit t prevent the bursting of the system due to overflow of current.
