Abstract
An electrical contact assembly includes a magnetic latch solenoid for actuating a moveable contact of a contact pair. The magnetic latch solenoid includes a magnet that latches the contact assembly in an open position, and a coil that moves an armature to the latched position under current in one polarity, and disrupts the permanent magnet field to release the armature from the latched position under current in a reverse polarity. A spring biases the contacts to the closed position. The spring is separate from the magnetic latch solenoid. The contact assembly may also include a printed circuit board for providing pulses to the coil to operate the assembly. The contact assembly is part of a remote operated circuit breaker assembly.
