2. Circuit breaker (overcurrent) - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker_(overcurrent)

   Vacuum circuit breakers—With rated current up to 6,300 A, and higher for generator circuit breakers application (up to 16,000 A & 140 kA). These breakers interrupt the current by creating and extinguishing the arc in a vacuum container – aka "bottle". Long life bellows are designed to travel the 6–10 mm the contacts must part.

3. Resettable fuse - Wikipedia

   en.wikipedia.org/wiki/Resettable_fuse

   A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch .

4. Generator interlock kit - Wikipedia

   en.wikipedia.org/wiki/Generator_Interlock_Kit

   Early generator interlock kits consisted of two sliding steel or plastic (depending on the brand) plates held together by three bolts and installed on the front cover of the home's breaker panel, however, some models made by Eaton (formerly Cutler-Hammer) and Siemens for panels manufactured by them install on the adjacent circuit breakers themselves and consist of a sliding arm for breakers ...

5. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

6. Vacuum interrupter - Wikipedia

   en.wikipedia.org/wiki/Vacuum_interrupter

   Generator switching applications are well known for their higher strains on interrupting devices, such as high fault current of high asymmetry or high and steep transient recovery voltage; the standard IEC/IEEE 62271-37-013 (former and still valid IEEE C37.013, 1997) was introduced to address such requirements on circuit-breakers used in ...

7. Crowbar (circuit) - Wikipedia

   en.wikipedia.org/wiki/Crowbar_(circuit)

   Thus the generator can ride through the fault and quickly continue the operation even during the voltage dip. The advantage of a crowbar over a clamp is that the low holding voltage of the crowbar lets it carry higher fault current without dissipating much power (which could otherwise cause overheating). Also, a crowbar is more likely than a ...
