The main advantage of how a thermal magnetic circuit breaker works is that it gives you both instantaneous and time delayed protection. A thermal circuit breaker is nothing but a bimetallic strip which uses the thermoelectric principle of heat generated while current passes through metals or for that matter any conductors.
While the generated heat reaches a certain value the thermally sensitive bimetallic strip bends tripping an actuator that breaks the circuit.

A thermal circuit breaker is nothing but a bimetallic strip which uses the thermoelectric principle of heat generated while current passes through metals or for that matter any conductors. Thermal magnetic circuit breakers contain two different switching mechanisms a bimetal switch and an electromagnet. Bulletin 1489 m thermal magnetic circuit breakers are ul 489 listed for branch circuit protection in the united states and canada and they are certified as miniature circuit breakers for iec applications.
