Technical characteristics |

The Italfarad Circuit Breaker is a device connected to the running capacitor of a single phase electric motor that provides an extra help when starting, staying connected for a very short time with an additional starting capacitor. It replaces the old starting methods like the centrifugal one, cumbersome and wearisome in fitting up. The Italfarad Circuit Breaker is largely adopted for several applications like electric motors for air compressors, washing machines, pumps and generally for all those applications in which the motor is supposed to overcome a considerable opposite mechanical torque. Currently there are 3 models: 2 electromechanical (ITF04 and ITF06) and 1 electronic (ITF02). |
