Wacker Neuson 5100007409 Fuse 40A

The Wacker Neuson Fuse 40A is a genuine OEM electrical protection component designed for the LTN4Y and LTN5Y series light towers, including LTN4Y, LTN4Y 60Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypk, and LTN5Ypa models. Sourced directly from Wacker Neuson, this fuse is manufactured to the exact amperage rating required by the machine's electrical system, ensuring consistent, code-correct overcurrent protection. Keeping the correct OEM fuse installed means your light tower's circuits are protected exactly as the engineers intended — no guesswork on ratings or form factor. Confirm your model number before ordering to ensure a direct match.

Key Features

• Correct 40A Amperage Rating — Matched to the precise overcurrent threshold specified for LTN4Y and LTN5Y series electrical systems, preventing nuisance trips and under-protection.
• Genuine Wacker Neuson OEM Part — Supplied directly from Wacker Neuson, this fuse meets the original design specification for part number 5100007409 with no substitution or approximation.
• Direct Drop-In Replacement — Engineered to fit the factory fuse holder on covered LTN4Y and LTN5Y variants without modification to the housing or wiring connections.
• Broad LTN Series Compatibility — Fits 14 distinct model configurations across the LTN4Y and LTN5Y families, including SA, RH, CH, UK, 60Hz, 120V/60Hz, Yp, Yp HD, Ypk, and Ypa variants.
• Electrical Safety Compliance — Using the correct rated fuse is critical in light tower applications; an incorrect amperage rating can leave downstream components unprotected or cause repeated circuit failures.

A fuse is a sacrificial overcurrent protection device that interrupts electrical flow when the current in a circuit exceeds a safe threshold — in this case, 40 amps. In a light tower like the LTN4Y and LTN5Y series, the fuse safeguards the generator output circuits, lighting controls, and connected electrical components from damage caused by overloads or short circuits. When a fuse blows, the protected circuit loses power entirely; installing a replacement of the correct rating restores operation and maintains the protection the system was designed around.
