⚙️ Key Features

🔌 Function

Protects its circuit by melting and breaking the supply when current rises above 20 amps, before the wiring or the component it feeds is damaged.

⚠️ Common Signs of Failure

• A circuit dead with no other symptom - instruments, pump or lamp simply stop working
• Element visibly melted, or the body smoke-blackened inside
• A replacement blowing straight away, which points to a short downstream
• Blade or holder clip discoloured and the holder running warm
• Fuse slack in its holder, giving an intermittent circuit

🛠️ Service Notes

• Never fit a higher rating to stop it blowing - the fuse protects wiring sized for 20 A, and the next failure will be in the loom
• A fuse that blows repeatedly is a symptom: find the short or overload before fitting another
• Check the holder clips for spring tension and corrosion, as a slack clip runs hot and cooks the fuse

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
