No illustration for this section
The Relay Box Assembly is listed without an exploded view in the SK250-8 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
The Kobelco SK250-8 Relay Box Assembly breaks down into 14 individually orderable part numbers. Callout numbers on the exploded view map one-to-one to the Ref. column in the table. Every entry is a genuine Kobelco part number, confirmed against the serial range before we quote.

Part numbers as fitted to the Kobelco SK250-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
The 14 entries group into 2 distinct number series, led by YN24E, YN24S. Expect repeated items such as fuse, relay, housing and 2 items fitted ten or more at a time when you work through it.
The high-quantity positions are: YN24E00016S005 (fuse (5a), ×11 per assembly); YN24E00016S008 (fuse (20a), ×10 per assembly); YN24E00016S006 (fuse (10a), ×9 per assembly). The full list follows below.
Monitor and controller items vary by machine build, so the serial number matters more in this group than in most. Send it with the fault description and we confirm the correct variant before quoting.
Electrical items are quoted with the condition declared: genuine through original supply channels, or a quality OEM alternative. For sensors and switches, genuine is usually the practical choice, and the quotation says which is which.
Yes — the harness is listed alongside its individual components, so you can replace a section or the complete assembly from the same table. If that matches your case, quote YN24E00016S005 and we will take it from there.
Send us the part number or a photo. Our coverage runs to 100,000+ part numbers available to order — this page lists one group, not the whole machine.
Yes. Connectors, relays and switches all carry their own part numbers in the table above, so a single connector repair can be quoted without a harness.
