Embodiment Construction

[0027] Embodiments disclosed herein describe an adapter module for an auxiliary trip device of a circuit breaker. Circuit breakers designed to accommodate auxiliary devices (such as sensors, alarms, remote trips, etc.) provide a cost-effective way for users to customize or reconfigure circuit breakers, and provide a cost-effective way for manufacturers to provide more Multiple product options to meet customer needs. As discussed above, these circuit breakers contain standardized "auxiliary bags" adapted to accommodate a variety of different modular auxiliary devices. In other words, the user can choose from several different auxiliary devices for a given circuit breaker. However, although circuit breakers of different sizes (e.g., different amperage ratings) may have auxiliary bags of the same standardized size, auxiliary trip devices are often specific to a specific circuit breaker, for example, in order to meet the tripping requirements of a given circuit breaker. Force an...

Abstract

The systems, equipment and methods for the auxiliary deduction and reset for the circuit breaker are disclosed.The embodiments of the present invention include the circuit breaker handle; the circuit breaker off the deduction; the auxiliary deduction device; the auxiliary bag configured as an auxiliary off -device; and the adapter moduleIn the auxiliary bag, it is coupled to the circuit breaker handle, circuit breaker off -bargain, and auxiliary deduction device. The appropriate instrument module contains a linkage device that is configured to increase the force output by the auxiliary device.Many additional features and aspects have been disclosed.

Description

technical field [0001] The present application relates to electrical circuit breakers, and more particularly to systems, devices, and methods for assisted tripping and resetting of circuit breakers. Background technique [0002] Generally, a circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by an overload or short circuit. If an overcurrent condition is sensed, the circuit breaker will automatically open its contacts. Therefore, circuit breakers include a trip unit that determines when to open the contacts. [0003] Some circuit breakers contain components for auxiliary devices such as sensors, alarms, remote trips, and the like. These circuit breakers contain standardized "auxiliary bags" adapted to accommodate a variety of modular auxiliary devices. Despite modularity and standardization, many auxiliary trip devices will not function properly in different sized circuit breakers. Accordingly, ther...
