An assembly for interacting with a circuit breaker operating mechanism of a circuit breaker, the assembly including an accessory device, an actuator, and a compliant device. The accessory device includes a plunger configured for movement between a retracted position and a protruded position. The actuator includes a first free end and a second free end, the second free end configured for mechanical cooperation with the plunger. The compliant device is disposed intermediate the operating mechanism and the actuator, the compliant device is configured for mechanical cooperation with the second free end of the actuator. A force is applied from the operating mechanism to the accessory device, the force for resetting the accessory device is transmitted from the operating mechanism to the compliant device, from the compliant device to the actuator, and from the actuator to the plunger for resetting the plunger from the protruded position to the retracted position.

A current sensing module for disposal proximate a conductor is disclosed. The current sensing module includes a housing having a first section and a second section that together define an opening for receiving the conductor therethrough. The second section is in operable connection with the first section. The current sensing module further includes a micro-electromechanical system (MEMS) based current sensor disposed within the first section proximate the opening for receiving the conductor.
摘要:
A fully automated circuit breaker saddle assembly in the form of a plastic support base having modular components that define the end and central sections of the support base. The components are snappingly fitted together and are retained by means of formations on the ends of the respective components. The metal circuit breaker stab assemblies are attached to the base by connectors integrally-formed in the base.
摘要:
Disclosed herein is an interlock system in combination with an enclosure, including: the enclosure having a base and a door that define an interior; a rotary handle attached to the door; a disconnect switch disposed in the interior of the enclosure and including a shaft extending toward an exterior of the enclosure in a direction toward the door; a first interlocking member attached to the door and extending toward an interior of the enclosure; and a second interlocking member attached to the shaft. The handle is configured to engage the shaft when the door is closed and rotate the shaft to move the disconnect switch between an on position and an off position. The second interlocking member is configured to engage and interlock with the first interlocking member when the door is closed and the disconnect switch is in the on position.
