摘要： A molded case current limiting circuit interrupter includes a pair of pivoting contact arms each supporting a contact and being connected to wiring terminals such that current flows through the contact arms in opposite directions. One of the contact arms has a movable pivot point. A magnetic drive slot motor device is provided to generate electrodynamic contact opening force upon the contact arms during short circuit conditions. A high-speed magnetic trip device releases the operating mechanism under short circuit conditions to move the arm pivot point before the contact arms reclose. A spring latch may be provided to latch the upper contact arm in a contact-separated position during short circuit conditions until such time as the overcurrent flow through the breaker operates a thermal and magnetic trip mechanism to move an operating mechanism to the tripped position. Alternatively, a cam may be provided which is connected by a link to the upper contact arm and positioned such that upon short circuit conditions the contact opening motion of the upper contact arm caused by electrodynamic repulsion forces will cause the connecting link to rotate the cam and move the armature of the magnetic trip device to actuate the trip mechanism and release the operating mechanism to the tripped position, thereby preventing reclosing of the contact arms before the operating mechanism is able to trip. The operating mechanism includes a bracket to allow normal contact reset yet provide a positive closed contact indication if the contacts are welded together. An anti-rebound contact arm shock absorber is provided which is made of material having a high mechanical hysteresis loop to provide maximum energy dissipation.

摘要： A multipole circuit breaker including a latch release actuator having a trip coil and a hold-in coil coaxially surrounding a plunger and mounted within a hollow cylindrical actuator support frame. The actuator is mounted in association with a latch mechanism and includes a spring biasing the plunger toward release of the latch mechanism. The hold-in coil is responsive to voltage conditions on an external control line and serves to oppose the action of the bias spring and maintain the plunger in a position to prevent release of the latch mechanism when the voltage on the control line is above a predetermined level. The trip coil is connected to an electronic sensing circuit which activates the trip coil upon overcurrent conditions through the circuit breaker contacts to cause the trip coil to aid the action of the bias spring and overcome the action of the hold-in coil to move the plunger into engagement with the latch mechanism, effecting release of the latch mechanism and separation of the circuit breaker contacts.

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.
