An overload protection system includes a panelboard and a load management system (LMS) which is configured to constantly measure the total amount of power being used at the panelboard such that when the total amount of energy measured is at or above a high programmed level, the LMS stops power from being supplied to a load and when the total amount of energy measured is at or below a low programmed level, the LMS allows power to be supplied to the load. The LMS includes a monitoring relay with a 'threshold hysteresis' built-in, which means that a threshold current at which an output switches from one state to another state is different depending on whether an input current is increasing or decreasing. The “threshold hysteresis” helps to eliminate noise and ensure that the output switches cleanly between ON and OFF, even if an input current level is fluctuating around a threshold current level.

Embodiments provide systems, apparatus, and methods for circuit breaker tripping. Embodiments include providing a circuit breaker with a thermoelectric tripping mechanism, the thermoelectric tripping mechanism including a thermoelectric plate disposed between a current path and a bimetal lever of the circuit breaker; applying a DC current to the thermoelectric plate to heat the bimetal lever; and deflecting the bimetal lever to press upon a trip bar in response to a current overload occurring on the current path. Numerous additional aspects are disclosed.
