Electric arc during circuit breaker closing in the distribution box
The arc between the circuit breaker contacts occurs due to the ionization of air, just as the air is ionized during a system short circuit. In short-circuit conditions, the arc flows from an energized conductor/component to ground or possibly phase-to-phase. An arc in a circuit breaker is a luminous electrical discharge—a plasma channel reaching temperatures of 20,000°C (36,000°F)—that forms between separating contacts when the breaker interrupts current under load. As the contacts separate, the current density between them increases, causing a rise in temperature and the. An Electric Arc is a visible plasma discharge that occurs when the medium (gas or air) between two separated contacts becomes highly ionized. They may be operated manually or automatically through the use of overcurrent protective devices (OCPDs).
