Phase 1 l2 l4.

3 phase reversing contactor wiring diagram. Figure 1 is a typical wiring diagram for a three phase mag. When a logic signal is applied to the forward terminal the gn0 switches l1 and l2 directly to. They can be used as a guide when wiring the controller.

This diagram is for 3 phase reversing motor control with 24 vdc control voltage. They show the relative location of the components. For more information see bulletin cf section.

Using this method the current is balanced between the 3 poles on the overload. Phase 2 l1 l2 l3. Includes mounting plate and hardware for assembly of reversing contactors.

Single phase wiring diagrams always use wiring diagram supplied on motor nameplate. The below wiring diagram shows how we would assemble a complete motor starter with a start stop button for a single phase motor utilizing a 3 pole contactor. Wiring diagram please contact your local rockwell automation sales office or allen bradley distributor bulletin b contactors 3 accessories see page for maximum number of auxiliary circuits.

Then you connect the 2 motor leads to t1 and t3. This directs the current through from l2 and directs it through the 3 rd phase on the contactor and overload l3 t3. To reverse rotation invert t5 and t8 o t5 t t2 o j tl t3 tl ti blue t2 white t3 orange t8 red t4 yellow t5 black m brown reverse rotation.

The neutral wire first goes to the thermal overload relay nc contacts and to the light indicator. In the above 3 phase motor forward reverse wiring diagram. 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.

From the 2nd thermal overload relay normal close contacts the supply goes to both contactors coil contacts terminals. Wiring diagrams sometimes called main or construc tion diagrams show the actual connection points for the wires to the components and terminals of the controller. And connect to both magnetic contactors a1 a1 terminals.
