What it is

FUSE 6.3 AMPS is a 6.3 amp antisurge HRC ceramic fuse supplied by Hamworthy under part number 533901221. It is fitted to a range of Hamworthy floor-standing gas boilers, including the Lillieput, Purwell, Shaftesbury and Warmwell families, where it serves as circuit protection. The fuse is rated at 6.3 A and must be matched to the rating specified in the appliance's documentation.

Before you order

  • Confirm the appliance calls for a 6.3 A fuse before ordering; do not substitute a different rating.
  • Check the part number 533901221 against the old fuse or the appliance's documentation.
  • Refer to the boiler's wiring diagram or manufacturer's literature to identify the correct fuse position.
  • Fuse ratings are application-specific; a higher or lower rated fuse may not provide the intended circuit protection.
