BS 5992-4 applies to contact assemblies of all types of relays covered by the Publication 255 series: Electrical Relays. BS 5992-4 specifies preferred characteristics of the contact loads to be used in endurance tests of electrical relay contacts over the ranges of voltages and currents defined by application categories. Preferred values are given for various types of load including relay and cables.
BS 5992-4 on electrical relays is helpful for:
Having access to reliable guidelines is essential to prepare and use quality electrical relays. BS 5992-4 provides manufacturers with the general requirements, terms and definitions along with the standard values which allows them to effectively manufacture and test electrical relays.
BS 5992-4 provides users with efficient and standardized electrical relays.
