Characteristics of permanent magnet AC contactor

Permanent magnet AC contactor is characterized by innovations permanent magnet drive mechanism to replace the traditional magnet drive mechanism, namely the use of permanent magnets and control device microelectronic modules, the replacement of the traditional products of electromagnetic devices, running without operating current, only by the weak signal

Flow (0.8-1.5mA). Microelectronics module contains six basic parts: 1. Power rectifier; (2) real-time detection  circuit breakers  supply voltage; 3. Release stored energy (some also have pull energy storage, but not necessary to have); 4. Energy storage capacitor voltage detection; 5. interference threshold voltage detector; 6. release

Put the logic circuit. This operating mechanism 6 is a permanent part of the control part of the necessary  circuit breakers  components, if any part is missing, the operating mechanism in a particular case would not be able to work properly. This six part, will determine the operating mechanism can have anti-shake electrical function.
