What it is

The Vaillant 0020127234 is a 6-pole terminal strip rated at 20A. It is used in the Vaillant geoTHERM VWL range of air source heat pumps to terminate and connect wiring within the appliance. The strip provides a secure, rated connection point for the conductors routed through it.

Signs this part needs replacing

  • Discolouration, charring or blackening around one or more terminals
  • Melted or brittle plastic on the strip body
  • Loose or slack connections that will not tighten down
  • Intermittent power or fault codes traced to the terminal block
  • Visible arcing marks or heat damage at the conductor entry points

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the existing strip for pole count and current rating before removal
  • Isolate the appliance from the electrical supply and verify dead before working on the wiring
  • Note the conductor positions before disconnecting, so wiring is reinstated correctly
