2 Replace the new contactor, and the distance between the surrounding metal conductors in the arc direction should not be less than the original contactor to avoid accidents. 3 When the contactor is used to automatically reverse the circuit, the action time of the reversible conversion of the replaced new contactor should not be greater than the arc burning time when the contactor is disconnected to avoid phase-to-phase short circuit. 4 After the replacement of the new contactor, its rated current, closing and breaking capacity can not be lower than the original contactor.
