“…The current limitation is done by a sufficient voltage build-up inside the breaker. The current path inside a CB is constructed in such a way that magnetic forces quickly move the arc into a set of metallic plates, making the arc split into a number of smaller arcs, each causing a voltage drop [16]. However, the current limiting circuit breakers only limit the current in case of actuation and always interrupt.…”

“…16) there is no problem in detecting and selectively isolating the fault from the main grid side by CB1.2, because the fault current seen by CB1.2 becomes higher I kmax ¼ 15 kA(Figure 4.17) than 13.5 kA(Figure 4.11) in the…”

Abstract. Miniature circuit breakers (MCBs) are widely used to protect electrical facilities within commercial, domestic and light industrial buildings. Arc motion in low voltage (240 VAC) high current (103-104A.) current limiting-circuit breakers is dominated by arc root mobility. In the recent years, computer image simulation of arc characteristics has important application in the investigation and development of technical low voltage MCBs.

“…In the electromagnetic model a symmetry plane is used as well. Because the 13 splitter plates are made of ferromagnetic iron, the magnetic field calculation has to consider the nonlinear relation between magnetic induction Thus the voltage drop depends on the local current density and leads to a delayed arc attachment at the splitter plates [16,2].…”

Polymer walls and inserts are an important design criterion in low-voltage switching devices. Besides their good insulation properties they are used to influence the switching arc. An important part of the energy dissipated in the arc is absorbed by the walls of the arc chamber. This leads to degradation and evaporation of the polymer and subsequent impact on and interaction with the switching arc. This contribution explains the enhancements of an existing simulation model for the interaction between the low-voltage switching arc and walls composed of polyamide PA 66. This includes a model of plastic ablation, the influence of the plastic vapor on the transport properties of the arc as well as on its radiation. Calculations and comparisons with experimental results show the applicability of the model in arc chambers that are close to reality.
