Q:What is the role of the contactor

Can be frequently connected with the high current control (up to 800A) circuit device, so often used in the motor as a control object, can also be used to control the plant

Q:How to choose the contactor

rated current multiplier refers to the motor starting current and rated current ratio, the general motor starting current is 5-7 times the rated current (RMS), converted to the peak, then the maximum to 12 times

Q:The Role of Virtual Instrument Technology in the Parameter Detection of Switchgear Cabinet

When the relay is off , The corresponding voltage is 0V, I / O port is "0". When the relay to add the magnetic voltage, the microcontroller to a small enough sampling cycle to read the corresponding digital I / O port,

Q:What is the power contactor

AC contactor using the main contact to open and close the circuit, with auxiliary contacts to control the implementation of instructions.

Q:Why should the thermal relay be used with the AC contactor

Thermal relay is used to protect the motor so that it is not overloaded, and motor-related, so with the use of the.

Q:Permanent magnet AC contactor main performance?
