Excavator Electrical Relay
If your Doosan excavator struggles with intermittent power loss, no-start issues, or unexplained battery drain, the Excavator Electrical Relay is often the hidden culprit.
As the main power switch between the battery and the machine's electrical system, this relay handles heavy current loads every time you start the engine. Over time, contact wear, heat damage, or corrosion can cause it to fail, leaving you stranded mid-job. This battery relay (part numbers 2544-9024 and 301202-00153) is built as a direct replacement for Doosan DH220-7, DH258-7, DH370, and DH420 excavators, restoring reliable power control.
Key Product Highlights
Heavy‑Duty Construction for High‑Current Use
Built with thick copper contacts and a sealed metal housing, this electrical relay is designed to handle the high starting currents of Doosan excavators without overheating or sticking under load.
Sealed & Vibration‑Resistant Design
The fully enclosed housing keeps out dust, moisture, and engine oil, while the rubber‑mounted bracket absorbs vibration. This ensures stable performance even in harsh site conditions.
Direct Fit for Quick Replacement
Matches the original mounting bracket and terminal positions exactly. No modifications to wiring or brackets are needed, so you can swap it in and get back to work quickly.
Factory‑Level Reliability to Prevent Downtime
Replacing a worn relay with this OEM‑spec part eliminates intermittent power drops and hard‑starting issues, protecting your machine's electrical system from voltage‑related damage.
Wide Compatibility with Multiple Doosan Models
Fits DH220-7, DH258-7, DH370, and DH420 excavators. A single part covers several common models, making it easy to keep in stock for repairs.
From our experience, replacing a worn relay early prevents more serious electrical issues down the line. A failing relay can cause voltage drops that damage sensors or even drain the battery overnight. Sticking with a reliable replacement like this one ensures your machine gets consistent power, reducing unexpected downtime.
