摘要： In a circuit interrupter which has multiple electronic trip circuits, such as ground fault and arcing fault trip circuits, indicators such as LED's produce an indication of the cause of the trip. The trip signals are latched to provide a continuing trip indication and ORed to actuate the trip device. In one embodiment SCR's connected in series with the indicator LED's serve as the latches and are connected in parallel to the trip device to provide the OR function. In other embodiments, flip-flops serve as the latches. In one such embodiment, the indicator LED's are connected from the respective flip-flops in parallel to the trip device to provide the OR function. In another such embodiment the flip-flops actuate the trip device and turn on switches actuating the LED's These switches energizing the cause of trip LED's are disabled until the contacts open to assure operation of the trip device. Alarms can be coupled to the trip circuit by additional LED's, preferably IR LED's, connected in series with the indicator LED's.

摘要： Apparatus for generating alarms for a group of circuit interrupters, especially those which respond to arcing faults, includes a device associated with each circuit interrupter providing an indication of a tripped condition and a common alarm generator which generates an alarm when any one, or at least any one of a number of selected circuit interrupters, is in the tripped condition. In one embodiment of the invention, switches indicating that associated circuit interrupters are tripped generate auxiliary trip signals on a common alarm bus. The auxiliary trip signals are latched by a latch on the common alarm bus which energizes a relay to activate a local and/or remote alarm. The latch is reset by a switch on the load center door. In another embodiment of the invention, an IR beam is blocked from reaching a photo-detector whenever a circuit interrupter handle is in the tripped position which also results in energization of a relay to actuate the common alarm. Selected circuit interrupters only can be alarmed by orienting the light beam such that only circuit interrupters selected by adding an extension to the handle block the beam when the associated circuit interrupter is tripped.

摘要： Ground fault trip units for circuit breakers are tested by a passive test circuit which includes a test conductor passing through the current transformer sensing coil(s), and a test switch which selectively connects the test conductor in a loop which simulates a neutral-to-ground fault. In a dormant oscillator ground fault test circuit, the test conductor loop passes through both sensing coils. When the neutral-to-ground detector is combined with a sputtering are fault detector sharing a common sensing coil, testing of all the components is accomplished by adding an additional test circuit which injects pulses derived from the line conductor into the sensing coil secondary, or which alternatively, connects a capacitor charged from a DC supply across the sensing coil secondary. Either of these alternative test circuits generates the successive events needed to produce a sputtering arc trip.

摘要： A ground fault circuit breaker includes separable contacts for interrupting current flow in a protected AC electric system when opened. The protected AC electric system includes a ground fault switch, such as a ground fault receptacle having a people protection ground fault trip curve, downstream from the ground fault circuit breaker. A current transformer generates an AC sensor signal representative of AC current flowing from the protected AC electric system to ground. A ground fault controller, connected to the current transformer, generates a ground fault trip signal as a function of the AC sensor signal and an equipment protection ground fault trip curve. A trip means, which is responsive to the ground fault trip signal, opens the separable contacts.

摘要： A multipole circuit breaker, for example, a three pole circuit breaker, can detect a condition when less than all of the phases are open circuited to trip the circuit breaker. This reduces the tripping time and hence risk of damage to the electrical load. The circuit breaker includes a thermal trip unit and a phase sensitivity assembly that is interlocked with the bimetals included with the thermal unit. The phase sensitivity assembly includes one or more levers, responsive to the deflection of a bimetal corresponding to the open circuited phase resulting from cooling action of a bimetal relative to the other bimetals. The relative displacement of the cooling bimetal is used to either trip or reduce the tripping time of the circuit breaker.

摘要： A circuit interrupter includes two parallel pivoting contact arms, the lower of which is connected to a stationary conductor member using a clinch-type contact. The contact arm has an axle member rigidly attached thereto which is supported by a bearing member attached to the conductor. In one embodiment, the bearing member comprises a pair of bifurcated arms which are clamped about each end of the axle member. In an alternative embodiment, the conductor member lies generally parallel to the lower contact arm and is slotted to form a pair of elongated conductor arms, each of which supports a journal bearing member. One end of the axle is extended through each journal bearing.

摘要： An actuator assembly for an electrical power switch apparatus, the actuator assembly having a housing and a plunger positioned within the housing where the plunger is movable between a set position and an actuated position. The plunger includes a compression spring to provide a pre-load thereto that biases the plunger away from the set position and toward the actuated position. A magnet contained in the housing and positioned proximate to the plunger establishes a magnetic force which overcomes the pre-load of the compression spring and maintains the plunger in a set position. A coil assembly, that when energized, produces an electromagnetic force which bucks the magnetic force established by the magnet allowing the plunger to be propelled by the compression spring to the actuated position. A screw extends through an opening in the plunger for engagement with the compression spring so that rotation of the screw results in the adjustment or calibration of the pre-load of the compression spring.
