Source: InternetPublisher:萌面大虾 Keywords: AC power electromagnet Updated: 2021/09/10
DW15-200-630A circuit breaker electromagnet adopts DC solenoid structure and short-time working system.
(1) The DK-1 control box uses an AC power supply solenoid closing
circuit as shown in Figure 6-74. DK-1 type is an electromagnetic control box. In the figure, SBi is the closing button, SBz is the opening
button, YA is the closing electromagnet coil, YR is the trip coil, KA is the intermediate relay, QF is the auxiliary contact of the circuit breaker,
Ri~R4 are the voltage equalizing resistors. Ci and C2 are energy storage capacitors.
