Q: How is the DC contactor connected to the circuit: with the benefits of contactor is easy to operate, reduce the risk factor when operating;

Q: What is the difference between a contactor and a circuit breaker?: the main circuit breaker to do protection, its protection is currently more commonly used is the three sections of protection, both overload protection, short circuit short delay, short circuit long delay.

Q: Permanent magnet AC contactor main performance?: If any part is missing, the operating mechanism can not work normally under certain circumstances.

Q: Dynamic Measurement Technology of Contactors and Comprehensive Evaluation Method: AC contactor dynamic test device to DSP as the core, build a variety of signal sensors, through the RS232 and the host computer for data communication.

Q: What is the formulation of the contactor?: contactor number of auxiliary contacts, and contactor installation options

Q: What about the number of AC contactors?: and the auxiliary normally open contact is disconnected , Thereby cutting off the power supply

Q: With long life, long reliability is the advantages of traditional communication contactor: closing speed faster than the traditional AC contactor, the detection, permanent magnet exchange Contactor closing time is generally less than 20ms, while the traditional contactor closing speed is generally about 60ms

Q: What causes the AC contactor to be damaged: Operation circuit power supply capacity is insufficient or disconnected, wiring error and control contact bad contact 3. The coil technical parameters are not in accordance with the conditions of use

Q: The Development of Electrical Performance Testing Technology for Contactors: The data processing in the literature mainly focuses on the calculation of power grid frequency and power factor
