What it is

The Chaffoteaux 61400290 is a temporized fuse rated at 250V and 0.5A. A temporized (time-delay) fuse tolerates brief inrush currents without rupturing, while still breaking the circuit under sustained overload. It is fitted to the listed Chaffoteaux SX FF gas boiler models as a circuit protection component.

Signs this part needs replacing

  • The boiler is completely dead, with no display or response to a demand for heat or hot water.
  • The fuse shows a visibly broken element or discoloured body.
  • Continuity testing across the fuse reads open circuit.
  • The boiler loses power again immediately after the fuse is replaced.

Before you order

  • Confirm the existing fuse is rated 250V 0.5A and is of the temporized type.
  • Check the appliance model against the fit list above before ordering.
  • Isolate the electrical supply to the boiler before removing or fitting the fuse.
  • If a replacement fuse blows again, investigate the underlying electrical fault rather than fitting another fuse.
