2. Inrush current limiter - Wikipedia

   en.wikipedia.org/wiki/Inrush_current_limiter

   The most popular application is the inrush protection of the AC current in switching power supplies (SPS). The primary reason for having surge current suppression in a SPS is to protect the diode bridge rectifier as the input or charging capacitor is initially charged. This capacitor draws significant current during the first half AC cycle and ...

3. Thermal cutoff - Wikipedia

   en.wikipedia.org/wiki/Thermal_cutoff

   Unlike a thermal fuse, a thermal switch is usually reusable and is therefore suited to protecting against temporary situations which are common and user-correctable. Thermal switches are used in power supplies in case of overload, and also as thermostats, and overheat protection in some heating and cooling systems. They are found in virtually ...

4. Selectivity (circuit breakers) - Wikipedia

   en.wikipedia.org/wiki/Selectivity_(circuit_breakers)

   The purpose of selectivity is to minimize the impact of a failure on the network. Faults in an installation are, for example, overload and short circuit. [1] [2] There are four ways in which selectivity is achieved: [3] Current selectivity: different breaking capacities; Time selectivity: time delay before tripping of a breaker

5. Overheating (electricity) - Wikipedia

   en.wikipedia.org/wiki/Overheating_(electricity)

   Circuit-breakers can be placed at portions of a circuit in series to the path of current it will affect. If more current than expected goes through the circuit-breaker, the circuit breaker "opens" the circuit and stops all current. A fuse is a common type of circuit breaker that involves direct effect of Joule-overheating.

6. Shunt (electrical) - Wikipedia

   en.wikipedia.org/wiki/Shunt_(electrical)

   If connected in series with the circuit it simply prevents reversed current, but if connected in parallel it can shunt the reversed supply, causing a fuse or other current limiting circuit to open. All semiconductor diodes have a threshold voltage – typically between 0.5 volt and 1 volt – that must be exceeded before significant current ...

9. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   All circuit breaker systems have common features in their operation, but details vary substantially depending on the voltage class, current rating and type of the circuit breaker. The circuit breaker must first detect a fault condition. In small mains and low-voltage circuit breakers, this is usually done within the device itself. Typically ...
