Hello Moat_asa
Yes ! - ClosingSoilenoid and Trip Solenoid - Both need a Short Pulse ( Like a Push Button ). You can withdraw the voltage across the coil once the operation has taken place.
Trip Coil will always have priority. In fact if you have Trip Coil energised and Closing coil is also energised, the Breaker will perform what is called an empty operation ( It starts to close but trips before the power contacts are half way close to each other ). Most ACBs have what iscalled the "Anti pumping Circuit" in the closing circuit to prevent repeated empty operations in case voltage remains applied to both Closing and Tripsolenoids. Hope this helps Cheers Navnag |
