3. Short circuit between turns. The solution is to replace the coil of the good price and quality 300A DC Contactor.
4. The working frequency is too high. The solution is to extend the working interval or replace the coil or 300A DC Contactor suitable for higher working frequency.
5. The magnetic pole surface of the AC iron core is uneven or the residual magnetic gap is too large, which causes the coil of the good price and quality 300A DC Contactor to heat up. The repair method is to clean the pole face or replace the iron core.
6. The double-winding coil of the good price and quality 300A DC Contactor is stuck due to the long-term adhesion of the closed auxiliary contact, and the starting winding is energized and heated for a long time. The repair method is to replace the self-locking contacts of the good price and quality 300A DC Contactor and eliminate the cause of the contact welding.
