About This Part
12V 30A solid state power relay for the 2026 BYD Sealion 06 EV (2026), 2026 Song L DM-i (2025-2026) and 2026 Sealion 05 DM-i (2025-2026), plus 18 further BYD models, under OE 12785197-00. This SSR, or automotive power relay, is a sealed plastic-cased blade-terminal switch that handles a 30-amp load with no moving contacts, giving quiet, arc-free switching for fuse-box circuits in the engine bay. Slot it into the fuse and relay box to cure a circuit that clicks, chatters or fails to power up.

Frequently Asked Questions: OE 12785197-00
The fitment list for this relay is long. How do I confirm it suits my car?
A long list tells you the part is used widely, and nothing more than that about your particular car. Start with the fitment table on this page and locate your model and variant in it rather than stopping at the marque. Then check the description against the unit you are replacing, because this listing is the solid state relay at 12V and 30A, and a unit of another rating is a different listing even where it looks similar. Where your variant is not clearly in the table, put the details to us through the quote route.
What is the delivery position on this relay?
Delivery takes 8 to 25 days from your order to your door. If you need to plan around a firm date, ask us to check the current position on OE 12785197-00 first. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the OE number on your old part against the one on this page.
What is the relay made of?
The material is plastic, which is the case around it. In practical terms that governs storage more than anything else, so leave it boxed until it is going on the car. What identifies the part is the description rather than the casing, so read the 12V and 30A solid state wording on this page against the unit you are taking out.
Where is this relay located on the vehicle?
Engine Bay. It sits under the bonnet rather than inside the car, which narrows the search considerably before you start. This listing is written for the Sealion 06 EV in the solid state form at 12V and 30A. Confirm your own model and variant against the fitment table on this page before ordering. If your car carries more than one relay of similar appearance and you cannot tell which is which, send the OE number 12785197-00 to us on the quote route and we will confirm what this listing covers.
Why does this relay come in one version only?
Only one version is available under OE 12785197-00, the Original/Genuine part from BYD, and there is no Aftermarket entry set up beside it. That is why the page shows one tier rather than two. It describes what we offer, not what the market as a whole does or does not produce. If somebody has offered you a substitute and you want it checked against this listing, send the reference through the quote route and we will look. If an Aftermarket line is added later, it will appear on this page.
