Source: InternetPublisher:睡不醒的小壮 Keywords: Control circuit motor contactor control AC contactor Updated: 2020/11/21
The motor contactor circuit is shown in Figure 3-117 and Figure 3-118. In Figure 3-117, if KMi and KMa use ordinary AC contactors (only
three main contacts), they can each use two contactors in parallel.
