BS EN 60669-2-4 is a British standard as a part of the IEC 60669 series that applies to manually operate general purpose isolating switches with a rated voltage not exceeding 440 V and a rated current not exceeding 125 A, intended for household and similar fixed electrical installations, either indoors or outdoors.
Note: Isolating switches are designed for overvoltage category III and used in the environment of pollution degree 2 according to IEC 60664-1
BS EN 60669-2-4 on isolating switches for household and electrical installations is useful for:
The electrical industry
BS EN 60669-2-4 provides you with guidelines for classification, marking, protection against electric shock, provision for earthing, and instructions for test methods to assess mechanical strength and resistance to heat. Using BS EN 60669-2-4 guidelines helps you with electrical testing, and dielectric strength tests and ensures performance, safety, quality assurance and prevents short circuits.
