A system includes any number of solid-state circuit breakers that couple between a power supply and an electrical load. The system also includes a housing and the solid-state circuit breakers are disposed within the housing. The housing includes a door sensor that generates a first signal indicative of a position of a door of the housing. The housing also includes an indicator that generates a second signal indicative of a position of a handle of the housing. The system also includes a secondary device communicatively coupled to the solid-state circuit breakers, the door sensor, and the indicator. The secondary device receives the first signal and the second signal and generates an instruction to adjust an operating state of the solid-state circuit breakers based on the first signal and the second signal.

Systems and methods for coordinating handle operations while operating solid-state circuit breakers

The present technology relates to multiple mode circuit and load protection devices configured to operate differently in each of the multiple modes. The protection device includes three power inputs and three corresponding power outputs. The protection device can be set to a motor protection mode or a circuit breaker mode. When set to the motor protection mode, the protection device detects a phase imbalance between the three inputs, analyzes electrical values associated with the three inputs and, detects a fault based on detecting a phase imbalance or detecting a failure based on one of the electrical values. When set to the circuit breaker mode, the protection device will disable measurement of or otherwise ignore phase imbalances and only detect a fault based on one of the electrical values. In response to detecting a fault, the protection device can trip, stopping current flow to load(s) coupled to the power outputs.
