1. A control system for a digital circuit breaker, the system comprising:
a digital circuit breaker;
an electric trace heater electrically connected to the digital circuit breaker, wherein the digital circuit breaker is to disrupt current provided to the electric trace heater based on a time-current curve;
a temperature sensor; and
a controller device in communication with the digital circuit breaker and the electric trace heater, the controller device including:
a processor in communication with the temperature sensor, the processor being configured to:
receive a temperature value from the temperature sensor,
construct the time-current curve for the digital circuit breaker based on the temperature value,
transmit data representative of the constructed time-current curve to the digital circuit breaker,
receive a new temperature value from the temperature sensor,
construct a new time-current curve for the digital circuit breaker based on the new temperature value, and
transmit new data representative of the new constructed time-current curve to the digital circuit breaker.
