2. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A Siemens air circuit breaker rated for 1000 V and 2500 A continuous current mounted on a motor control cubicle. Medium-voltage circuit breakers rated between 1 and 72 kV may be assembled into metal-enclosed switchgear line-ups for indoor use or may be individual components installed outdoors in a substation.

3. Breaking capacity - Wikipedia

   en.wikipedia.org/wiki/Breaking_capacity

   Types used in commercial and industrial low-voltage distribution systems are rated to safely interrupt 200,000 amperes. The rating of power circuit breakers varies according to the application voltage; a circuit breaker that interrupts 50,000 amperes at 208 volts might be rated to interrupt only 10,000 amperes at 600 volts, for example.

4. Sulfur hexafluoride circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Sulfur_hexafluoride...

   Generator circuit breaker rated for 17.5 kV and 63 kA. Generator circuit breakers (GCB) are connected between a generator and the step-up voltage transformer. They are generally used at the outlet of high-power generators (30 MVA to 1800 MVA) in order to protect them in a reliable, fast and economic manner.

5. Slash rating - Wikipedia

   en.wikipedia.org/wiki/Slash_rating

   The slash rating, under the United States National Electrical Code, is given to circuit interrupt hardware and specifies a maximum line-to-ground voltage rating in combination with a maximum line-to-line voltage rating.

6. Automotive fuse - Wikipedia

   en.wikipedia.org/wiki/Automotive_fuse

   Automobile electrical circuit breaker with resettable switch. Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive ...

7. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   At two multiples of the rated current, the recloser's rapid trip curve can cause a trip (off circuit) in as little as 1.5 cycles (or 30 milliseconds). During those 1.5 cycles, other separate circuits can see voltage dips or blinks until the affected circuit opens to stop the fault current.
