What it is

The Hamworthy 533901205 is a five-pin base for a volt free relay, also listed as a single pole relay base, reference ZD1. It holds the relay and provides the terminal connections between the relay pins and the boiler's control wiring. It is supplied with a retaining clip.

Signs this part needs replacing

  • The relay sits loose in the base or will not clip in securely
  • Intermittent boiler operation traced to poor contact at the relay base
  • Scorching, discolouration or brittle plastic around the terminals
  • Cracks in the base housing
  • The retaining clip is missing or broken

Before you order

  • Confirm the relay has five pins
  • Check the existing base is marked ZD1
