Overview — Fuse 6A-3C 249-0856
249-0856 is the 6A-3C fuse used on CUMMINS equipment to protect the specified electrical circuit, opening the circuit at the rated current to prevent wiring and component damage. We can supply this fuse as well as related CUMMINS electrical parts, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The fuse is rated for the original 6A current with the 3C characteristic, sized to match the holder and the circuit it protects. The body is molded to the original dimensions and the contacts fit the standard holder. The fuse element opens cleanly at the rated load without nuisance tripping at normal operating current. As an OEM-spec fuse, it restores the designed protection level for the circuit.
Applicable Models & Applications
This fuse is used on CUMMINS engines and equipment in the electrical circuit specified for the 6A-3C rating, including control circuits, sensor supplies and instrument feeds. The reference 249-0856 identifies the fuse for the relevant circuit on the engine or machine. Confirm the current rating, characteristic and holder type against the fuse removed from your equipment before ordering.
Maintenance & Replacement
A blown fuse indicates a circuit fault, so check the wiring and components for the cause before replacing the fuse. Look for short circuits, damaged insulation and failed components on the protected circuit. When replacing, use the correct rating and characteristic, seat the fuse fully in the holder, and confirm the circuit operates normally. Never fit a higher-rated fuse to mask a fault, since it removes the protection from the wiring.
