A multi-purpose mounting assembly is provided. The multi-purpose mounting assembly is structured to be disposed in an electrical switching apparatus housing assembly. The multi-purpose mounting assembly includes a body defining a first mounting assembly and a second mounting assembly. The first mounting assembly includes a first mounting construct. The second mounting assembly includes a second mounting construct. The first mounting construct is structured to support a first electrical component. The second mounting construct is structured to support a second electrical component.

A trip assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, an electrical communication assembly coupled to the housing, separable contacts enclosed by the housing, and an operating mechanism for opening and closing the separable contacts. The trip assembly has an indication assembly including a plunger member and a number of auxiliary switches each structured to be coupled to the housing. The plunger member is structured to actuate each of the number of auxiliary switches, thereby electrically communicating a circuit status to the electrical communication assembly.

A delay time generation apparatus for an air circuit breaker according to the present invention can provide an effect of ensuring a delay time as long as possible even in a narrow space upon outputting a signal related to a conductive state, by virtue of interaction of a main shaft, a pin portion, a first rotating unit, a second rotating unit and a spring member.

A circuit breaker having a first micro switch, a second micro switch and a transmission mechanism. The transmission mechanism drives the first micro switch and the second micro switch, which are arranged in a circuit breaker shell. The first micro switch and the second micro switch are arranged on one side of the shell side by side, and a corresponding first transmission rod and a corresponding second transmission rod in the transmission mechanism respectively drive the first micro switch and the second micro switch. Since the circuit breaker is provided with no external device, the space occupied by the circuit breaker is reduced, thereby facilitating construction and installation. Since the two micro switches are built-in side by side, different signals can be simultaneously output.

An accessory device for a circuit breaker. The device includes a housing having a top wall and a hinge portion. The device also includes a plunger arm that extends from the hinge portion to form a cantilever wherein the plunger arm includes a first surface and a sloped surface. The plunger arm is moveable between an initial position wherein the plunger arm does not activate the first and second switches located in the housing and a deflected position wherein the first and sloped surfaces simultaneously contact the first and second switches, respectively, thereby activating the first and second switches. The plunger arm also includes a plunger portion that is oriented transverse to the plunger arm. A mating surface is formed on the plunger portion that mates with a mating surface of a circuit breaker operating mechanism. Further, the housing, hinge portion, plunger arm, and plunger portion are integrally formed.

The trip assembly includes an actuating element structured to be coupled to the housing and structured to be electrically connected to the electrical communication assembly; and an indication assembly cooperating with the actuating element in order to electrically communicate a circuit status to the electrical communication assembly.

Disclosed in the present invention are a linkage mechanism, a base, and a surge protection device. The linkage mechanism comprises a linkage swing rod and transmission components, wherein the linkage swing rod is arranged to be rotatably connected, and is provided with a trigger portion capable of triggering a switch when rotating and at least two stress portions arranged spaced apart from each other on one side of an axis of rotation of the linkage swing rod; one transmission component is arranged corresponding to each of the stress portions; and the transmission components are arranged in such a way that any of the transmission components applies a pushing force to the stress portion to rotate the linkage swing rod, and thus the trigger portion triggers the switch. According to the surge protecting device using the linkage mechanism provided in the present invention, a module failure signal can be sent out when any surge protection module fails under the condition where only one microswitch is arranged, which not only simplifies the structure of the surge protecting device and reduces the volume, but also reduces the cost.
