What it is

The terminal block cover is a Potterton Commercial casing component for the Sirius 2 and Sirius 3 range of gas boilers. It is designed to sit over the boiler terminal block, closing off the electrical connection point within the casing assembly. The part is supplied under Potterton part number 5141435.

Signs this part needs replacing

  • The cover is cracked, broken or missing from the terminal block area
  • Fixing points or retaining clips are damaged so the cover will not seat
  • Heat discolouration or deformation has left the cover unable to close correctly
  • The cover no longer shields the terminal connections as intended

Before you order

  • Confirm the boiler model against the fit list, as Sirius 2 and Sirius 3 variants differ
  • Check the existing cover for the part number 5141435 where it is still legible
  • Inspect the terminal block and its fixings for damage before fitting a new cover
