A thermal breaker is advantageous in situations where systems face overload conditions because it is designed to respond to the heat generated by excess current flowing through the circuit. When an overload occurs, the increased temperature causes a bimetallic strip inside the breaker to bend and trip the circuit, interrupting the flow of electricity. This mechanism allows the thermal breaker to provide reliable protection against sustained overloads that might not be immediate short circuits.

In scenarios where short circuits are common, magnetic breakers offer faster reaction times because they are designed specifically to trip nearly instantaneously upon detecting a large surge of current, making them more suitable for protecting against such events. Cost considerations may lean toward other types of breakers depending on the specific requirements and installations, as there are various options available on the market. When a quick reset is needed, magnetic breakers are also preferred because they typically trip faster and can reset quickly compared to thermal breakers, which may need time to cool down before they can be reset after an overload.

Thus, the context of overload conditions emphasizes the thermal breaker's effectiveness in safeguarding the system against prolonged high current situations, making it the better choice in that specific circumstance.
