The YM W8008-2 is a robust, high-performance starting relay engineered to handle the extreme current demands of heavy-duty applications. Designed for 12V, 24V, 36V, and 48V DC systems, this relay is the critical link between low-current control switches and high-power loads like engine starters, winch motors, and preheating systems. Built to withstand harsh environments in trucks, ships, and industrial vehicles, the W8008-2 ensures reliable power delivery for mission-critical starting operations, making it an indispensable component in any heavy-duty power relay system.
Model: W8008-2 | Coil Voltage Options: DC 12V, 24V, 36V, 48V | Type: Heavy Duty Starting Relay
This heavy-duty relay is engineered for the most demanding starting and high-power switching tasks:
Manufactured under strict IATF-aligned quality controls, each W8008-2 relay is tested for performance and durability. We offer OEM customization, including different terminal types (spade, screw, stud), custom branding, and specific coil resistance values. We can also collaborate on developing variants for emerging new energy commercial vehicles.
Q1: What is the main difference between this starting relay and a standard 40A automotive relay?
A1: This is a high power relay switch designed for intermittent, high-inrush current duty (like starting motors). It typically has much larger contacts, heavier internal construction, and is rated for the physical and electrical stress of starting cycles, whereas a standard relay is for continuous lower-current loads like lights or fans.
Q2: Can this relay be used for continuous duty, like powering a light bar?
A2: While capable, it is over-specified for such tasks. For continuous duty, a relay rated for 100% duty cycle at the load current would be more cost-effective. The W8008-2 is optimized for short, high-power bursts.
Q3: Is a diode required on the coil for this relay?
A3: Highly recommended, especially in vehicles with sensitive ECUs. When the coil is de-energized, the collapsing magnetic field creates a high-voltage spike that can damage the control circuit. A diode suppresses this spike—a fundamental principle in electrician u relays and automotive electronics.
Q4: How does it compare to a Solid State Relay (SSR) for this application?
A4: For starting applications, an electromechanical relay like the W8008-2 is generally preferred. It offers much lower contact resistance (less voltage drop), can handle massive inrush currents, and is cost-effective for high-current switching. SSRs can fail short-circuit and generate significant heat at these current levels.
Q5: Do you offer this relay with a mounting bracket or socket?
A5: The standard model is designed for direct screw mounting. However, we can provide custom mounting solutions or refer you to compatible industrial relay sockets as accessories industrial power relay options for specific OEM integration needs.
