WebThermal A thermal breaker, as it sounds, works with heat. Current (amps) creates heat as it passes through the breaker, if the breaker gets too warm, it opens a switch that is normally spring loaded to open the circuit and stop the electrical current. Advantages: Less expensive and has a time delay as the breaker heats up.

"WebA thermal-magnetic OCPD is an OCPD that reacts to the heat created by the copper loss (I2R) when current passes through a conductor. Copper loss is caused by the resistance of the conductor to a current passing through it. This loss is expressed as heat. The higher the current flow through a conductor, the more heat is created.
