A control system and methods for a digital circuit breaker are provided. The system comprises a digital circuit breaker, an electric trace heater electrically connected to the digital circuit breaker, a temperature sensor, and a controller device in communication with the digital circuit breaker and the electric trace heater. The controller device includes a processor in communication with the temperature sensor, and the processor is configured to receive a temperature value from the temperature sensor, construct a time-current curve for the digital circuit breaker based on the temperature value, and transmit data representative of the time-current curve to the digital circuit breaker.

Rail

A mounting rail is provided that includes a DIN rail and one or more heating cable channels. A channel defined by the DIN rail may include one of the heating cable channels. Heating cables may be installed in the heating cable channels using adhesive and/or heat transfer material to form an electronics heating module. The heating cables may be self-regulating heating cables. The mounting rail may include multiple heat transfer fins that transfer heat generated by the heating cables to environment surrounding the mounting rail. A terminal block may be mounted on the DIN rail and may supply electric power to the heating cables.

Apparatus for electronic component and heating cable mounting

A power converter for heat tracing applications is disclosed. The power converter includes a controller configured to control an input switching stage. The power converter also includes an output filter, the output filter electrically coupled to the input switching stage. Further, the power converter includes a passive cooling element, the passive cooling element coupled to the power converter. The controller is configured to select a peak voltage and set a power converter output voltage based on at least one of the peak voltage and a power converter input voltage. The passive cooling element is configured to decrease a temperature of the power converter and to obviate the need for cooling with moving parts, making the system viable for hazardous areas in addition to non-hazardous areas. The input switching stage includes a plurality of transistors. The power converter output voltage and the power converter input voltage are both alternating current.
