Which term includes fuses, current limiters, thermal protectors, and circuit breakers?

Explanation:
The main idea here is that these items are all used to protect an electrical circuit from damage by interrupting or limiting current when something goes wrong. Fuses are sacrificial elements that melt open when the current is too high, permanently opening the circuit. Circuit breakers sense overcurrent and trip to disconnect the circuit, and they can be reset after the fault is fixed. Current limiters actively cap the maximum current to prevent excessive flow, even in fault conditions. Thermal protectors monitor temperature and disconnect the circuit if overheating occurs. Together, these components are all circuit protection devices. The other options don’t describe devices that interrupt or limit electrical current in a circuit: noise refers to unwanted electrical signals, an ESD control program addresses protecting parts from static discharge, and a conductive wrist strap is a tool used to prevent ESD while handling components.
