Main and auxiliary circuit diagrams of switching three-phase
May 16, 2022A circuit diagram is broken down into the main circuit and the auxiliary circuit (control circuit and signalling circuit). The various circuits are represented separately from left to right in this sequence (Figure 2). The equipment designations are not only used to identify the complete devices themselves, but also to identify all the used contacts and terminals of each

Notes: This circuit is known as a latching circuit, because it “latches” in the “on” state after a momentary action. The contact in parallel with the “Run” switch is often referred to as a seal-in contact, because it “seals” the momentary condition of the Run switch closure after that switch is de-actuated. The follow-up question of how we may make the motor stop running is a
