65 Amps 4 Pole AC Contactor 24V/110V/220V Coil

4 pole AC contactor relay, 65amps, 24V/110V/220V coil voltage for selection, 4P (4NO) or 4P (2NO+2NC) contact form. As a bypass contactor, it is widely used for long-distance connecting and breaking circuit.

Tips: Coil overheating or burning, how to solve?
Possible Causes:

• The power supply voltage is too high or too low.
  
• Line technical parameters (such as rated voltage, frequency, load factor and applicable working system, etc.) do not match the actual use.
  
• Operating frequency is too high.
  
• Insulation damage due to poor coil manufacturing or mechanical damage.
  
• The moving part is stuck.
  
• The AC core is uneven or the magnetic air gap is too large.
  
• AC contactor derives the double coil of DC operation, because the normally closed interlocking contact welding does not release, and the coil is overheated.
  

Processing method:

1. Adjust the power supply voltage.
   
2. Exchange coils or contactors.
3. Select other suitable contactors.
4. Replace the coil to remove the obstacle that causes mechanical damage to the coil.
   
5. Specially designed coils.
6. Eliminate jamming.
7. Clear the pole face or change the core.
8. Adjust the interlocking contact parameters and replace the burnt coil.
