Using Komatsu WA500-3H Wheel Loader Wiring Harness (Slow Blow Fuse) Parts
Use the Komatsu WA500-3H Wheel Loader Wiring Harness (Slow Blow Fuse) Parts listing to identify aftermarket replacement parts within the electrical system section. This wheel loader application is listed for machine serial H20051 - UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 11 listed part occurrences, including fuse, 80amp. (reference 421-06-22820), fuse, 120amp. (reference 421-06-22830) and fuse, 30amp. (reference 421-06-22840). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
For electrical parts, compare the component reference and any voltage, connector or equipment-option notes shown in the listing. A similar description or shape alone is not a compatibility check.
Catalog quantities describe the illustrated assembly. Adjust the order quantity to what you need, select the relevant rows, and use Add selected to cart for verified store matches or Add selected to quote for quote items. The diagram alone does not establish current stock or part interchangeability.
