2. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   Medium-voltage circuit breakers can be classified by the medium used to extinguish the arc: 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".

   The neutral wire is connected to the neutral busbar to the left with all the white wires, and the two hot wires are attached to the main breaker. Below the main breaker are the two bus bars carrying the current between the main breaker and the two columns of branch circuit breakers, with each respective circuit's red and black hot wires leading ...

   High-voltage switchgear A section of a large switchgear panel. Tram switchgear This circuit breaker uses both SF 6 and air as insulation.. In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.

5. Utilization categories - Wikipedia

   en.wikipedia.org/wiki/Utilization_categories

   The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions.

6. High-voltage switchgear - Wikipedia

   en.wikipedia.org/wiki/High-voltage_switchgear

   Circuit breakers are essential elements of high-voltage power systems because they are the only means to safely interrupt a short circuit current. The international standard IEC 62271-100 defines the demands linked to the characteristics of a high voltage circuit breaker. [7] The circuit breaker can be equipped with electronic devices to know ...

8. 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 ...
