Chinese term or phrase: 不可逆接触器
As in "4个Allen Bradley 100-c60d10 不可逆接触器,负责为供给装置电机、供给装置电机供电。“

后文中还有”可逆接触器“,英文应该是"directional contactor",那不可逆就是"non-directional contactor"?

Thank you, guys.

Explanation:
不可逆与可逆接触器:
Non-Reversing vs. Reversing Contactor

解释如下:

A non-reversing contactor is just a single contactor, with three main switching terminals (1 per phase for a 3-phase supply to the motor.)

A reversing contactor is an assembly of two of the above, with a mechanical and electrical interlock between them, so only one contactor can be closed (giving power supply to the motor) at any time. The Forward/Reverse - Up/Down - Left-right etc. are usually opposite motions, and the opposite motions are obtained via labelled switching buttons which energizes the coil of the correct contactor, mechanically locking the other motion contactor and also electrically preventing it from closing.

In the standard 3-phase squirrel-cage rotor motor, the reverse motion is easily obtained by swapping any two of the 3 phase wires to the motor, which then runs in the opposite direction = reverse.
