3 Phase Reversing Contactor Wiring Diagram. 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. It uses two contactors two auxiliary contact blocks an overload relay a mechanical interlock two normally open start pushbuttons a normally closed stop pushbutton and a power supply with a fuse.
When a logic signal is applied to the forward terminal the gn0 switches l1 and l2 directly to. Includes mounting plate and hardware for assembly of reversing contactors. In the above 3 phase motor forward reverse wiring diagram.

Input modules and reversing contactors 42 type s ac magnetic starters 43 50 class 8536 43 50 8538 and 8539 45 49. Using this method the current is balanced between the 3 poles on the overload. And connect to both magnetic contactors a1 a1 terminals. This diagram is for 3 phase reversing motor control with 24 vdc control voltage.
