Product Description
Product Introduction
This 40A Double Relay WG9716582301+009 is an OEM electrical control component for heavy-duty trucks (e.g., Sinotruk Howo series). It features a robust black plastic housing with a 5-pin terminal block, clearly marked with standard automotive relay pin numbers (30, 85, 86, 87, 87a). Engineered as a double-pole, double-throw (DPDT) relay, it is rated for 40A current capacity, making it suitable for controlling high-power electrical systems. Manufactured to strict OEM specifications, it ensures reliable performance in high-vibration, dusty, and corrosive environments.
Core Function
-
High-Power Circuit Control: Acts as a double-pole switch to control two separate high-current electrical circuits (e.g., dual motors, auxiliary lighting, or heavy-duty actuators) using a single low-current control signal, simplifying the vehicle’s electrical architecture.
-
Versatile Switching Modes: The DPDT design allows for both normally open (NO) and normally closed (NC) circuit configurations, providing flexibility for various control applications.
-
Overcurrent Protection: The 40A rating provides robust overcurrent protection, preventing damage to the relay and connected components in the event of a short circuit or overload.
-
Durable Construction: The sealed plastic housing and gold-plated terminals resist corrosion, dust, and moisture, while the heavy-duty internal contacts ensure stable electrical connections under heavy vibration.
-
Perfect Compatibility: Strictly adheres to OEM design standards, featuring a standard 5-pin automotive relay footprint for seamless, plug-and-play installation, ensuring full system compatibility with the vehicle’s electrical control system.
