    摘要: An arc hood includes a housing having a first chamber with two ends, a top and a bottom having an opening, and a smaller second chamber disposed on the top of the first chamber. The smaller second chamber includes two ends, a top and a bottom. Each of the ends of the second chamber have an opening, are disposed above the top of the first chamber, and are recessed from a corresponding one of the ends of the first chamber. The chambers define a passageway between the opening of the bottom of the first chamber and the openings of the ends of the second chamber. One or more baffles are within the housing and are disposed between the opening of the bottom of the first chamber and the openings of the ends of the second chamber. A seal is disposed about the opening of the bottom of the first chamber.

    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.

    摘要: A circuit interrupter includes a circuit breaker mechanism having a trip coil energized by a current transformer to separate the contacts upon command of a microcomputer-based trip unit during overcurrent conditions. A bimetallic normally-open thermal switch is mounted on the internal conductors of the breaker and is connected in parallel with the trip unit to energize the trip coil when the conductors overheat. The thermal switch is also connected to the interrupt terminal of the microcomputer to cause appropriate display and alarm information upon activation of the thermal switch.

    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: 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.
