ALLNET ALL16881PC Powerline Phase Coupler / RCD Signal Bridge for 3-Phase Systems, DIN Rail Mount, 4 TE, 230/400V AC

Bridge powerline signals across all three phases and over residual-current devices with the ALLNET ALL16881PC. This passive coupler operates at 230/400V AC and mounts on a DIN rail in just 4 TE, making it a compact solution for whole-building powerline networks.

Overview

The ALL16881PC is a phase coupler and RCD signal bridge designed for three-phase electrical installations. It connects L1, L2, L3, and N via screw terminals, ensuring powerline communication signals reach every circuit even when RCDs are present. The device is passive, requiring no power supply, and is built for universal powerline standards such as HomePlug AV and G.hn.

What stands out

• Couples powerline signals across all three phases
• Bridges signals over RCDs (FI-Schutzschalter) that would otherwise block them
• Passive design – no power consumption
• Compact DIN rail mount, only 4 TE wide
• Supports 230/400V AC, 50/60 Hz
