Abstract: A method for operating a stored energy circuit breaker actuation apparatus comprising the step of selecting from among manual locked, manual unlocked or automatic operations. If manual unlocked operation is selected, the method further comprises the steps of selecting local or remote operation. If local operation is selected, the stored energy circuit breaker actuation apparatus may be used by depressing a local ON switch and to turn off the circuit breaker assembly by depressing a local OFF switch and operating an operator handle. If remote operation is selected, the circuit breaker assembly may not be turned on or off. If manual locked operation is selected, the method comprises the further steps of selecting local or remote operation. The stored energy assembly may not be used to turn the circuit breaker assembly on or off either remotely or locally. If automatic operation is selected, the method comprises the further steps of selecting local or remote operation.

Abstract: A stored energy apparatus for association with an operating handle of a circuit breaker contains springs that store energy when charged and that release energy when discharged. Energy is stored when a movement translation assembly is moved in a charging direction by an operator gear, and stored energy is released when a release apparatus releases the operator gear, causing the movement translation assembly to move in a discharging direction. The circuit breaker operating handle is moved to ON position by the charging movement of the movement translation assembly, and as stored energy is released, the discharging movement of the movement translation assembly moves the operating handle to OFF position. The operator gear is operated via an operator handle, operator shaft, and pinion gear assembly. The pinion gear assembly has a carrier pivotally associated with the operator shaft and a pinion gear that rotates the operator gear.

Abstract: An improved PTC current limiting composition has been provided which comprises a chemically cross-linked thermosetting polyester resin and conductive particles dispersed in the resin. The thermosetting polyester resin is selected from the group consisting of polyethylene glycol fumarate, polypropylene glycol adipate fumarate, neopentyl glycol isophthalate fumarate, and neopentyl glycol phthalate fumarate. The conductive additive particles are selected from the group consisting of graphite and/or carbon black. The composition exhibits PTC behavior when cross-linked by a vinyl monomer selected from the group consisting of styrene, vinyl toluene and tertiary butyl styrene. Curing proceeds by free-radical addition across double bonds of the thermosetting polyester resin and is initiated by organic peroxides. Initial gelation which causes cross-linking but not final curing takes about 0.5 to 4 hours at a temperature of about 25.degree. C. to 125.degree. C. The final cure takes about 0.

Abstract: An electrical contactor has first and second contacts movably mounted to engage for achieving continuity in an electrical circuit, via an electromagnet and armature defining a magnetic circuit with an air gap that closes in a first position of the contactor and opens in a second position of the contactor. A controller switches an alternating current voltage to the coil of the electromagnet during a timed portion of each AC half cycle, and senses the current level in the coil in a feedback loop. The controller adjusts the voltage-on time to achieve a predetermined average current as needed for accelerating the armature or coasting during a closing operation, for holding the armature in place when closed, etc. In order to sense whether the contactor is presently open or closed, the controller monitors and stores the phase angle between the previous voltage zero crossing and the time of voltage turn-on.

Abstract: A gear motor assembly is disposed in a support structure in such a manner that it may rotate in a plane perpendicular to the output shaft thereof. Stops are provided for preventing the shaft from turning past a predetermined point. The motor assembly is located in the support structure by a resilient leaf spring which deflects when the stops are engaged.

Abstract: A U-shaped heater unit is surrounded by a U-shaped bimetal, the legs of which move in response to temperature variations. The motion of the bimetal is conveyed through a wall by a slidable pin which acts to rotate an L-shaped compensator element. This rotation lifts a link element which operates a switch when the trip point is reached. A reset mechanism includes a plunger which when manually depressed rotates a reset arm first in one direction to reset the switch after it has been tripped and then in the opposite direction to a neutral station in which it will not reset the switch. The reset mechanism thus cannot be defeated by jamming the plunger in its fully depressed position.
