ABSTRACT:
A transfer switch includes a miniature circuit breaker housing, a first line terminal, a second line terminal, a load terminal, and separable contacts electrically connected to the first line terminal. A transfer arm is electrically connected to the load terminal and is adapted to move between a first position in which the transfer arm is electrically connected to the separable contacts and a second position in which the transfer arm is electrically connected to the second line terminal. A solenoid having a first coil, a second coil and a plunger moves the transfer arm between the first and second positions thereof. An operating mechanism opens and closes the separable contacts.
