Overview

EN 50065-4-6:2023 - Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz - Part 4-6: Low voltage decoupling filters - Phase coupler (CLC) specifies requirements for phase couplers used in mains communication systems. The standard applies to utility networks and household, residential, commercial and light industrial fixed installations. It defines electrical, EMC and safety requirements to ensure reliable coupling of communication signals between phases or sections of a low-voltage mains communication system while preserving the safety of the electrical installation.

Key Topics and Requirements

• Scope and purpose
  • Controls coupling of PLC/mains communication signals between phases or network sections.
  • Ensures minimum inter-phase coupling and no adverse effect on safety.
• Classification
  • Type 1 (standard type) - coupling typically via capacitors; higher mains-frequency leakage current; usage may be limited by safety considerations.
  • Type 2 (low leakage type) - coupling typically via transformer; designed for low mains-frequency leakage.
• Mains frequency leakage current
  • Measured at nominal voltage per the standard test setup (each phase terminal tested independently).
  • Limits: Type 1 ≤ 0.5 mA (r.m.s.), Type 2 ≤ 200 µA (r.m.s.).
• Operating frequency range
  • Utility phase couplers: 3 kHz to 95 kHz
  • Consumer phase couplers: 95 kHz to 148.5 kHz
• Transfer function and impedance
  • Maximum attenuation between phase terminals measured according to EN 50065-4-1; manufacturer specifies allowable attenuation.
  • Impedance measurement procedures referenced to EN 50065-4-1; modulus requirements ensure correct loading behavior.
• EMC immunity and safety
  • EMC immunity requirements referenced to EN 50065-2-1, -2-2 or -2-3 depending on environment (residential, industrial or utility).
  • Safety requirements referenced to EN 50065-4-2.
• National variations
  • Annex A includes special national conditions (e.g., Norway’s IT distribution system note).

Applications and Users

Who uses EN 50065-4-6:

• Manufacturers and designers of phase couplers and low voltage decoupling filters for powerline communication (PLC).
• Utility companies deploying mains communication across multi-phase networks.
• Electrical installers and integrators specifying compliant mains communication couplers in residential, commercial or light industrial projects.
• Test laboratories validating leakage, impedance and transfer performance to EN 50065 series methods.

Practical benefits:

• Ensures consistent inter-phase signal coupling for PLC systems.
• Reduces interference and maintains user safety by limiting mains-frequency leakage.
• Provides harmonized test and classification criteria for market access in CENELEC member countries.
