What it is

The protection switch fuse 20A, part PLS6-C20/3, is a Worcester Bosch electrical protection component rated at 20A. It forms part of the appliance's safety circuit, protecting the boiler's electrical supply against overcurrent faults. It is fitted across the Greenstore combi and system boiler family.

Signs this part needs replacing

  • The boiler has no power or will not start, with the supply confirmed live at the isolation point
  • The fuse shows no continuity when tested
  • The fuse fails again shortly after replacement, indicating a fault elsewhere in the circuit
  • Visible damage or scorching to the fuse body or its holder

Before you order

  • Confirm the appliance model against the fit list above
  • Check the rating marked on the existing fuse matches 20A
  • Verify the Worcester Bosch part number 87445030200 against the component being replaced
  • Investigate the cause of failure before fitting a replacement, as a fuse that blows repeatedly points to an underlying electrical fault
