3 Phase Reversing Contactor Wiring Diagram. And connect to both magnetic contactors a1 a1 terminals. The figure below shows schematic diagram for industrial three phase wiring.
From the 2nd thermal overload relay normal close contacts the supply goes to both contactors coil contacts terminals. Input modules and reversing contactors 42 type s ac magnetic starters 43 50 class 8536 43 50 8538 and 8539 45 49. And connect to both magnetic contactors a1 a1 terminals.
In the above 3 phase motor forward reverse wiring diagram.

The figure below shows schematic diagram for industrial three phase wiring. 1 phase 2 phase 4 wire 3 phase line markings l1 l2 l1 l3. The three phase supply shown in the diagram l1 l2 l3 which is connected to the mccb circuit breaker and after that the supply goes to the magnetic contactor and from the contactor the supply goes to the thermal overload relay and from the thermal overload relay the supply goes to 3 phase motor.
