Abstract: A four-pole molded case circuit breaker is provided with connecting rods for simultaneously driving the contact arms in all four poles while at the same time allowing for a staggered contact depression in the fourth pole relative to the other three poles. A stabilizer clamp locks the connecting rods together to eliminate relative motion between the rods without interfering with the staggered contact depression. By staggering the contact depression in the fourth pole, a three-pole operating mechanism can effectively toggle a four-pole device since the load of the contact depression springs in all four poles is not seen by the operating mechanism at the same time.

Abstract: A circuit interrupter handle mechanism is disposed on the face of a molded case circuit breaker. The handle mechanism has a rotary handle, which may be rotated through approximately 90° of rotation from a disposition of circuit interrupter conduction to a disposition of circuit interrupter non-conduction. The handle is not centered over the linear handle of the circuit interrupter per say, but rather is disposed in the upper left hand corner, so that a larger lever arm can be utilized. Furthermore, the larger lever has a handle opening into which the hasp of a lock may be placed to lock the circuit breaker in the open state for servicing and the like. Because of the length of the handle more hasps can be disposed therein than if the handle was disposed exactly in the center of the circuit breaker case. Lastly, the disposition of the circuit breaker rotary handle provides an indication of the conduction status of the molded case circuit breaker. If the handle is in a generally horizontal position, i.e., straight across the front of the circuit interrupter, that is an indication that the contacts of the circuit interrupter are open and that current therefore is blocked. If on the other hand the handle is 90° displaced, in a rotational manner, to be parallel with the long longitudinal axis of the circuit interrupter, then an indication is given that the circuit interrupter contacts are closed and current is being conducted.

Abstract translation: 电路断路器手柄机构设置在模制外壳断路器的表面上。 手柄机构具有旋转手柄，其可以从电路断续器导通的位置旋转大约90°的旋转到电路断续器非导通的布置。 手柄不是位于电路断路器的线性手柄上方，而是位于左上角，从而可以使用较大的杠杆臂。 此外，较大的杠杆具有手柄开口，锁可以放置在其中以将断路器锁定在打开状态以进行维修等。 由于把手长度设置在断路器壳体的中心，所以手柄的长度可以更多地设置在其中。 最后，断路器旋转手柄的布置提供了塑壳断路器的导通状态的指示。 如果手柄处于大致水平的位置，即直线穿过电路断路器的前部，这表明电路断路器的触点断开，并且电流因此被阻塞。 另一方面，如果手柄以旋转方式90°位移与电路断路器的长纵轴平行，则指示电路断路器触点闭合并且正在传导电流。

Abstract: Multi-pole circuit breakers are joined together to form a common assembly. The individual poles are in the form of compact circuit breakers having a pair of separable contacts controlled by a single externally-accessible operating handle. The individual circuit breakers are riveted together and are keyed such that the contacts open and close in unison. The individual handles are interlocked together by means of a unitary plastic handle tie.

Abstract: Each breaking module is formed by a parallelepipedic monoblock cartridge made of plastic material, housed in the corresponding compartment of the base plate, said cartridge housing at least a stationary contact, an arc extinguishing chamber, and a pair of connecting strips for connection to a terminal and to the trip module of the same pole. A mechanical actuation module constituted by the switching bar and mechanism assembly, is securedly united to the cover. The rotary trip bar is supported by clipping means, arranged on the bottom face of the cover. A plurality cf recesses and cutouts are arranged in the spacers of the base plate to act as first bearing surfaces respectively for the switching bar and trip bar when the first sub-assembly A composed of the base plate with the set of breaking modules and trip modules, is adjoined with the second sub-assembly B formed by the cover on which the mechanical actuation module, trip bar and latch are fitted.

Abstract: A modular crossbar arrangement for molded case circuit breakers allows a plurality of contact arm assemblies to be interconnected from a single modular unit. To provide increased acceleration to the movable contact arms a contact arm accelerator lever interfaces with the contact arm and crossbar assembly. To promote further acceleration of the movable contact arms to their closed positions, the movable contact arms in a multi-pole circuit breaker are staggered with respect to their rotational alignment within each pole on the crossbar assembly.

Abstract: A multi-pole circuit breaker apparatus includes first and second circuit breakers having first and second handles extending therefrom for switching the circuit breakers between "On" and "Off" positions. The circuit breakers are connected together with the handles extending generally parallel to each other. A handle tie connects the first and second handles for simultaneous operation. The handle tie has first and second handle openings disposed therethrough. The first and second handles extend all the way through the first and second handle openings, respectively, so that a forwardmost extension of the combined handles and handle tie is no greater than a forwardmost extension of the handles in the absence of the handle tie. The handle tie is slidably received about the handles so that it is free to float along at least a portion of a length of the handles. This provides a multiple circuit breaker apparatus which can readily fit into all existing enclosures in which the circuit breakers could fit in the absence of the handle tie.

Abstract: An electric current-limiting circuit breaker comprises a pair of separable contacts and a selective solid state trip unit including an actuator cooperating with a latch mechanism for actuating the contacts to a positive open position upon occurrence of an overcurrent condition. The movable contact may also be moved by electrodynamic repulsion towards the open position when the fault current exceeds a predetermined threshold to effect current limiting. A tripping control device has an electronic counter which counts successive opening and closing cycles of the contacts so as to trip mechanism after a given number of cycles. The trip unit further comprises a first time delay tripping circuit, and a second instantaneous tripping circuit which cooperates with the cycle counter so as to ensure either instantaneous tripping or tripping by counting up to a number of cycles preselected on a setting selector.

Abstract: The present invention relates to a multi-pole circuit breaker with an interchangeable magneto-thermal tripping unit electrically and mechanically connected to the breaker unit by means of connecting screws. The connecting lugs of the breaker unit are positioned with vertical play in transverse slots in the breaker unit casing and are electrically connected to the movable contacts by flexible connections. When the connecting screws are tightened the breaker unit connecting lugs are shifted to bear on the associated tripping unit lugs irrespective of any positioning defects. A reset spring of the electro-magnetic tripping device is anchored on one end on the armature and on the other end to the tripping device adjusting bar.

Each of the automatic trip devices respectively includes an actuator member secured to a latching member thereof and extending toward a latching member of an adjacent automatic trip device.
