There isn't one definition, a thermal circuit could be one that resonds to temprature, for example while current flows through a circuit breaker it gets warm, to much and it gets hot and mechanically trips and must be reset when cool.
Thermal circuit could be used to describe any circuit that responds to temprature for example a diode in a tuned circuit that changes in capacity based on temprature when used as a V V C.

A thermal circuit breaker is a safety device which breaks an electrical circuit if the temperature gets too high. These devices are used to prevent fires, damage due to voltage fluctuations, and other dangerous electrical situations. Many people are familiar with thermal circuit breakers because they may have them in their homes, or they may use a thermal/magnetic circuit breaker, which contains two failsafes to open a circuit in the event that a problem develops.
Circuit breakers work by detecting hazardous conditions in an electrical circuit and opening that circuit so that it cannot be completed. As long as the circuit is open, electricity cannot flow through it, and thus the opening of the circuit eliminates a hazardous situation. Once the problem which caused the breaker to open has been addressed, the breaker can be reset, closing the circuit and allowing it to work again. If the breaker is reset without addressing the problem, there is a high probability that it will trip again.

Thermal circuit also may be the path of the heat to be ejected out, or used as "thermal agent circuit" - the heat conducted and bared by some caring agents by pipes to heat some other parts away from the location of heat producing.
