How many magnetic contactor use for forward reverse?

For a forward-reverse motor control system, typically two magnetic contactors are used. One contactor is designated for the forward direction, while the other is for the reverse direction. This configuration allows for safe and efficient switching of the motor's rotational direction, while ensuring that both contactors cannot be energized simultaneously to prevent short circuits or damage. Additionally, auxiliary contacts may be employed to ensure proper interlocking between the two contactors.
