Not all solenoids are created equal. In AC breakers solenoids are wound such to minimize noise (hum) and optimize reaction time at AC currents. Some are not fast enough reaction time and so are coupled with external stimuli and motors to break the circuit. We use motorized breakers on our transmitter as certain fault conditions must remove power in less than one cycle of the power line. The power supply for the transmitter is capable of sustained loads of close to 50 kW.
