Low-voltage surge protective devices - Surge protective devices connected to low-voltage power distribution systems. Selection and application principles Ingestion-build-205840 Couplings covered by this International1 Scope This Technical Specification describes the principles for selection, operation, location and co ordination of SPDs to be connected to 50 Hz to 60 Hz a. c. power circuits and equipment rated up to 1 000 V r. m. s.. NOTE 1 This Technical Specification deals only with SPDs and not with SPDs components integrated inside equipment. NOTE 2 Additional requirements may be necessary for special applications such as electrical traction, etc. NOTE 3 It
