Wacker Neuson 5100013954 Fast Fuse, 5A, 250V, 5 x 20mm

The Wacker Neuson Fast Fuse, 5A, 250V, 5 x 20mm is a genuine OEM component designed for the HI260 and HI1000 series indirect air heaters. Sourced directly from Wacker Neuson, this fuse meets the exact electrical specifications required by the original design — 5 amps, 250 volts, in the standard 5 x 20mm form factor. It fits a broad range of HI1000 configurations including diesel, gas, and DGM variants, as well as the HI260 oil heater with tank. Drop-in replacement with no modifications needed to the fuse holder or circuit board.

Key Features

• Correct Electrical Rating: — Rated at 5A and 250V in the 5 x 20mm format, matching the circuit protection specification of the original fuse exactly.
• Genuine OEM Part: — Supplied by Wacker Neuson as part number 5100013954, ensuring the component meets the same standards as the fuse installed at the factory.
• Broad Heater Compatibility: — Fits HI260 and HI1000 series heaters across multiple configurations, including diesel, gas, DGM electric brake, and DGM surge brake models.
• Fast-Blow Protection: — Designed to interrupt the circuit immediately on overcurrent events, protecting sensitive control electronics in your heater from damage caused by voltage spikes or wiring faults.
• Electrical Safety Compliance: — Using the correct rated fuse is essential for safe heater operation; substituting an incorrectly rated fuse risks damage to control boards or creates a fire hazard in the heater enclosure.

A fast-blow fuse acts as the first line of defense in a low-voltage control circuit, cutting power the instant current exceeds the rated threshold. In indirect air heaters like the HI260 and HI1000, the control circuit manages ignition, fuel delivery, and safety shutoffs — all functions that depend on stable, protected power. When this fuse fails or is blown, the heater will not start or will shut down unexpectedly; fitting the correct 5A, 250V, 5 x 20mm replacement restores the circuit to its designed protection level and gets the heater back in service.
