A network of interconnected circuit protection devices in a datacenter that can communicate over a network. Each circuit protection device can have a management component such that each device could know the state of every other device or a centralized management component could know the state of all devices. The states of the protection devices could include, fault or non-fault (e.g., high-current, current-imbalance and high temperature). Using this information, the management component(s) can prevent a single-device failure from triggering circuit-protection devices in other sections of the data center to open. The breaker logic can operate such that if a single device short-circuited and all devices upstream in the power delivery system sensed the short-circuit, then the lowest-level device would open and if the fault was still detected upstream, then the next level device would open.
