Spring charge motors are DC operated Motor for operating Stored energy Mechanism used to energies (for closing or opening or Trip ) the breaker. These are used in Low voltage Air circuit Breaker,MOCB(Minimum oil circuit Breakers ) Vac *** Breaker ,HV breakers, MOCB, SF6 breakers(Motoraised Actuator used) Etc. It is normally available in 48v DC,110v DC, 220v DC Universal Motors.This will charge the Breakers within a minutes,If manually charge it will take>3to 5 min.It is used for Auto closing /Remote Start Application in process Industries , various Generation to Distribution Substation.Breaker operation will be very fast (less 1 sec).these stored energy is always available in Breaker while closing or tripping by solenoid coil only , with suitable control circuits.With these capabilities Automation Industries work efficiently without any down time . These breaker are not at all operated manually except test purpose.

Depends on the circumstances. However, some large circuit breakers, for example, are designed to be moved quickly by a spring, and the spring charging motor tensions that spring.
Also occurs in some emergency doors, shutters etc., which are shut by a large spring when triggered, the charging motor carries out the same task as above.

The motor to charge the spring .Thus charged spring stores the ptential energy which is used operate the quick mechanisms e.g. opening or closing circuit braker contacts
