⚙️ Key Features

• 40 A rating
• Listed for 41 applications on the DPX range
• Supersedes 3884849
• Included in the engine harness
• 2 used per assembly

🔌 Function

Protects its circuit by breaking the supply if current rises above 40 amps, so a fault cannot burn the harness or the equipment behind it.

⚠️ Common Signs of Failure

• The circuit it protects dead, with everything else working normally
• Element melted or the body darkened inside
• A new fuse failing immediately, pointing to a short rather than a worn fuse
• Holder or blade clips discoloured and warm to the touch

🛠️ Service Notes

• It comes as part of the engine harness, so a replacement harness already carries one
• Never fit a higher rating to keep a circuit alive - the fuse is protecting cable sized for 40 A
• Find and clear the fault before fitting a replacement; repeated blowing is the symptom, not the cause
