Tips: Reasons for the contacts of contactor being unable to separate after powering off

Control line of the coil is too long, the residual voltage is too large due to the influence of lead capacitance, which is enough to maintain a close situation for the iron core. As a result, the contacts can't be separated.
Coil of the contactor has burnt out, deformed coil skeleton seizes the movable iron core, which makes it unable to move, thus the contacts can't be separated.
The contact has been fused.
The contactor has auto-lock function, and the function is normal.

DC Reversing Contactor for DC Motor Forward/Reverse Control
The reversing type of DC contactor has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks. In this video, ATO will show you how to use a DC reversing contactor for the DC motor forward and reverse control.

Electromagnetic Switches: Relays VS. Contactors

In this video we will try to clear the confusion many people have between relays and contactors by showing you how to tell the difference based on five criteria: Definition, Capacity, Structure, Contacts and Applications.

400A DC reversing contactor worked fine

The DC reversing contactor worked fine, but after replacing it, my winch still didn't work. Found out it was corroded battery terminals that was causing the problem. Cleaned them up and it worked. Only complaint would be that it is a little pricey.
