ELECTROMECHANICAL TYPE B03 – B05

The ELECTROMECHANICAL type B0 circuit breaker is a device who connects a START CAPACITOR (that can be integrated with the device) to the permanent RUN CAPACITOR during the starting phase when a HIGH TORQUE is required and disconnects it after a prefixed time (standard 1”).
Lifetime of B0 depends on several factors like the capacitance of Start Capacitor, the tension measured on the run capacitor, operating time, frequency end temperature : the higher those values, the shorter the lifetime of device.
Vice versa an higher pause between consecutive starts preserves its correct working for a longer time.
B0 circuit breaker is largely adopted in several applications such as compressors, floor sweepers, high-pressure cleaners, pumps, coffee grinders, chainsaws and generally for all those applications where the motor is supposed to overcome a considerable opposite mechanical torque.
