Overview

This part of VDE 0170 specifies the special requirements for the design, construction, testing and marking of electrical equipment and Ex Components with type of protection increased safety "e" intended for use in explosive gas atmospheres. Electrical equipment and Ex Components of type of protection increased safety "e" are either: - Level of Protection "eb" (EPL "Mb" or "Gb"); - or Level of Protection "ec" (EPL "Gc"). Level of Protection "eb" applies to connections, conductors, windings, lamps, and batteries, but not electronic components. Level of Protection "ec" applies to connections, conductors, windings, lamps, and batteries; and also including semiconductors and electrolytic capacitors. The requirements of this standard apply to both Levels of Protection unless otherwise stated. For Level of Protection "eb", this standard applies to electrical equipment where the rated voltage does not exceed 11 kV r.m.s., a.c. or d.c. For Level of Protection "ec", this standard applies to electrical equipment where the rated voltage does not exceed 15 kV r.m.s., a.c. or d.c. This standard supplements and modifies the general requirements of DIN EN 60079-0 (VDE 0170-1). Where a requirement of this standard conflicts with a requirement of DIN EN 60079-0 (VDE 0170-1), the requirement of this standard takes precedence. Due to the large number of changes to the previous draft, it was necessary to publish it again as a draft. The responsible Committee is DKE/K 241 "Schlagwetter- und explosionsgeschützte elektrische Betriebsmittel" ("Electrical apparatus for potentially explosive atmospheres") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
