Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz - Low voltage decoupling filters. Phase coupler Ingestion-build-156411 The test applies to laboratory1 Scope This European Standard applies to phase couplers in a mains communication system for phase to neutral voltage not exceeding 250 V a. c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings. This European Standard applies to phase couplers used to control the coupling of communication signals between phases or sections of a mains
