of rated ultimate short-circuit breaking capacity Icu

- we recommend to coat the busbars with paint- input and output conductors/busbars must be reinforced mechanically to eliminace transfer

of electrodynamic forces into circuit breaker/switch-disconnector at short-circuits see fi g.

Reduced rated current IRSpecifi cally established, reduced value of In current for a regulated time-dependent (thermal) release, and that the circuit breaker can handle continuously. Maximum setting is at value equal to In. Changing Ir shifts the release’s tripping characteristic along the current axis. Ir = k x In holds where k ≤ 1

Pollution degree relates to the conditions of the surrounding environment for which the device is intended.Pollution degree:1 - No contamination will occur, or only dry, non-conducting contamination.2 - Normally occurs only non-conducting contamination, but sometimes there may occur temporary conductibility

due to condensation.3 - There occurs conductive contamination or dry non-conducting contamination that with the eff ect of condensation

will become conductive.4 - Contamination generates continuous conductibility, by means of, for example, conductive dust, rain or snow.
