Overview
This International Standard is applicable to mechanical switching devices designed as "circuit-breakers for equipment" (CBE) for household and similar applications. Circuit-breakers for equipment according to this standard are intended to provide protection to circuits within electrical equipment including its components (for example motors, transformers, internal wiring). This standard covers also circuit-breakers for equipment applicable for protection of electrical equipment in case of undervoltage and/or overvoltage. This standard also covers circuit-breakers for equipment which are suitable for isolation. This standard contains all the requirements necessary to ensure compliance with the operational characteristics required for these devices by type tests. It also contains the details relative to test conditions and methods of testing necessary to ensure reproducibility of test results. This standard specifies: a) the characteristics of circuit-breakers for equipment; b) the conditions with which circuit-breakers for equipment shall comply, with reference to: 1) their operation and behavior in normal service; 2) their operation and behavior in case of overload; 3) their operation and behaviour in case of short-circuits up to their rated short-circuit capacity; 4) their dielectric properties; c) the tests intended for confirming that these conditions have been met and the methods to be adopted for the tests; d) the data to be marked on the devices; e) the test sequences to be carried out and the number of samples to be submitted for certification purposes (see Annex C); f) the routine tests to be carried out to reveal unacceptable variations in material or manufacture, likely to affect safety (see Annex J). The responsible body is DKE/UK 541.2 "Kleine Selbstschalter" ("Miniature circuit-breakers") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
