41 3 phase reversing contactor wiring diagram
3: Simplified GN0 Motor-Reversing SSR wiring diagram As can be seen from figure 3 above, two of the three phases are wired through the GN0 and the third phase is connected directly to the motor. When a logic signal is applied to the "forward" terminal, the GN0 switches L1 and L2 directly to . AC Motor Control Circuits AC Electric Circuits. Each of the two different motor starters powers the motor with a different phase rotation. When the forward contactor is energized, power contacts connect line L1 to T1, line L2 to T2 and line L3 to T3 at the motor. When the reverse contactor is energized, the power contacts connect line L1 to T3, line L2 to T2 and line L3 to T1 at the motor. The reversing contactor is a kind of special product that can be built by combining two standard contactors by use of a mechanical interlock unit. Reversing contactors are designed for demanding forward/reverse operating of three-phase AC motors. Typical applications of these products are con...
