Reversive motor starter LT4-B-D 40A/400V 50Hz

A reverse starter, also known as a reverse motor starter or reverse contactor, is a type of motor control circuit that allows you to reverse the direction of rotation of an electric motor. It is commonly used in applications where a motor needs to operate in both forward and reverse directions, such as conveyor systems, winches, cranes, and certain types of machinery. The reverse starter achieves motor direction reversal by changing the phase sequence of the motor is power supply. There are two sets of contactorsﾗone for the forward direction and another for the reverse direction. Each set consists of a main contactor and auxiliary contacts. Interlocking Mechanisms prevent both forward and reverse contactors from being energized simultaneously, avoiding short circuits and ensuring safe operation. Reverse starters are commonly used when a motor-driven system needs to operate in both directions. They offer a simple and effective way to achieve motor direction reversal without manual intervention or complex wiring changes. It is important to ensure proper interlocking mechanisms and safety measures to prevent accidental or unsafe operation.
