There are a number of devices that break a circuit. On motor circuits an overload block opens the circuit when the motor's current goes above the motor's nameplate rating. Likewise a fuse or a breaker will open a circuit when the current goes above their rated limit. In home wiring circuits the home devices are controlled by a simple on- off switch. Electric heating circuits are controlled by thermostats that regulate the heaters by opening and closing the heater's supply voltage.
