What it is

The Heatline 3003201782 is a 3.15A slow blow (time-delay) fuse supplied under the Heatline brand. It is a consumable electrical protection component used in boiler circuits, where a slow blow characteristic allows brief inrush currents to pass without rupturing the fuse element. This listing is for a pack of ten fuses.

Before you order

  • Confirm the failed fuse carries the same 3.15A slow blow rating as this part before ordering.
  • Check the physical fuse size and end cap type against the fuse holder on the appliance, as fuses of the same rating are made in different body sizes.
  • Verify how many fuses are required so the pack of ten covers the job.
  • Ensure the circuit is isolated and the fault that caused the fuse to rupture has been identified before fitting a replacement.
