Motor run capacitor series MRC are capacitors designed for continuous operation of single phase induction motors. Permanently connected to the motor coil's terminals the capacitors are subjected to a voltage higher than the main voltage and so supply to the system the suitable reactive power needed to run correctly. Manufacturers of washing machines, dryer machines, refrigerators, pumps, air conditioning systems, can select the MRC series capacitors available in metallic casing equipped with an overpressure safety device or in simple flame retardant plastic case enclosures. Attention should be paid to the selection criteria of the AC motor run capacitors so that specified operating conditions and permissible loads such as the rated voltage, working temperature and life time of capacitors are not exceeded. Our MRC capacitor series can also be used for operation with a three phase motor on single phase connection system.
