DAMA WM686 4‑Pin 12V 120A Automotive SPST Heavy Duty Relay for Automotive / Motorcycle / ATV High Current Switching | Pack of 1

The DAMA WM686 4-Pin Split Charge Continuous Duty SPST Relay is a high-capacity electrical switching solution designed for dual-battery setups and high-current power routing, available at HID Concept.com. This Single Pole Single Throw (SPST) heavy-duty relay is rated to switch currents up to 120A. Constructed with Silver Tin Oxide (AgSnO) contact material, it features a design with very small contact wear-outs over its operating life. This configuration features little risk of contacts arcing, which helps protect against ignition concerns in areas where fuel fumes may be present, such as in boat engine compartments or specialized automotive setups.

Key Features & Benefits

• SPST Configuration: Features a standard 4-pin Single Pole Single Throw layout designed for high-current circuit integration.
• 120A Switch Current: Rated for a 120A switching current, making it highly capable of managing heavy-duty power routing applications.
• Silver Tin Oxide (AgSnO) Contacts: Built with high-grade AgSnO contact material to provide electrical conductivity and reduce contact wear.
• Reduced Arcing Risk: Designed with a small risk of contact arcing, helping protect against ignition concerns where fuel fumes may be present.
• Fast Response Times: Delivers an exceptionally quick 15 ms operating time and a 10 ms release time for precise electrical control.
• Wide Operating Range: Performs consistently under severe conditions, with a rated operating temperature range of −22°F to +176°F.

Vehicle Compatibility Section

This heavy-duty 4-pin SPST relay is compatible with 12V DC electrical systems (with a maximum applicable voltage of 14V). It is commonly used in campervans, boats, automatic car starting systems, and split-charge battery applications. Please verify that your specific configuration runs on standard 12V nominal power and requires a 120A switching capacity before wiring.

Performance & Visibility Section

Maintaining a reliable path of electricity is essential for high-current vehicle electrical accessories. The DAMA WM686 relay functions as a heavy-duty automatic switch that connects or isolates circuits based on your system triggers. While this passive relay does not generate light or alter headlight beam patterns directly, it plays a vital role in ensuring that high-draw vehicle accessories, split-charge setups, or starter systems receive the electrical connection required to operate.

OEM Quality & Reliability Section

Under-hood components are subjected to challenging conditions, including high ambient heat and vibration. The DAMA WM686 heavy-duty relay is built to operate reliably across a broad temperature spectrum of −22°F to +176°F, providing a dependable solution for auxiliary power setups. Sourcing your electrical hardware through HID Concept.com ensures you receive high-quality construction designed to support your vehicle's power management needs.

Installation Information

The DAMA WM686 relay features a 4-pin terminal layout to facilitate straightforward electrical integration. In a standard setup, the layout consists of control circuit connections to trigger the internal switch and primary terminals to route the high-current load. Ensure all wiring is properly insulated, protected by appropriate fuses, and that the relay is securely mounted in a dry location clear of direct heat sources or moving mechanical parts.
