Abstract: Devices and methods for on-the-fly updates of circuit breakers during operation, the circuit breaker including a processor, a first memory including a first and second slot, and a second memory. In response to initialization, the processor stores a copy of a most recent firmware from the first or second slot in the second memory and executes the most recent firmware at the second memory. The firmware in the first or second slot may be a first firmware, and in response to obtaining a second firmware, the processor stores a copy of the second firmware in the other of the first and second slot. In response to a second initialization, the processor stores a copy of the second firmware from the other of the first slot and second slot in the second memory to enable execution of the second firmware, the second firmware being the most recent firmware.
