12V 30A Quick Connect Relay ONLINE LED STORE PSZACCEPS179R with Fuse

Description

Product Overview

The 12V 30A Connect Relay from ONLINE LED STORE is engineered for demanding automotive applications where reliable high‑current switching is essential. Featuring a quick‑connect terminal block, the relay eliminates the need for complex soldering, allowing installers to snap the unit into place with a single motion. The internal contacts are crafted from silver‑plated copper, delivering superior conductivity and reduced contact resistance, which translates to longer service life even under continuous cycling.

Designed to operate at a nominal 12 V DC system voltage, the relay can handle up to 30 amps of continuous current, making it ideal for powering headlights, fog lights, auxiliary pumps, and other accessories. A built‑in 30 A blade fuse, housed in a heavy‑duty 14 AWG wire harness, provides over‑current protection, safeguarding both the vehicle’s electrical system and the relay itself. The coil resistance of 80 milliohms and a coil voltage of 12 V ensure fast and reliable actuation, while the normally open (NO) contact configuration guarantees that the load remains off until the relay is energized.

Physical dimensions of 6.5 × 5.62 × 2 inches and a lightweight design (12.8 oz) allow the unit to fit comfortably in tight engine bays or panel‑mount locations. The product carries the UPC 816165023880 and ASIN B01NBAO1SA, confirming its authenticity and traceability within the ONLINE LED STORE catalog. Whether you are upgrading a classic vehicle or outfitting a modern truck, this relay offers a blend of durability, performance, and ease of installation that meets the rigorous standards of automotive enthusiasts.

Usage

This relay excels in a variety of automotive scenarios. For drivers who frequently add aftermarket lighting, such as LED strips or high‑intensity discharge (HID) headlights, the 30 A rating provides ample headroom to prevent voltage drops and flickering. It is also perfectly suited for powering auxiliary devices like electric winches, fuel pumps, or cooling fans that demand consistent current without overheating the wiring.

Installation is straightforward: connect the four‑pin SPST (single pole single throw) harness to the vehicle’s power source, trigger line, and load circuit, then secure the relay to a panel using the provided mounting brackets. The quick‑connect design reduces wiring time by up to 50 % compared to traditional screw‑terminal relays, making it a favorite among professional mechanics and DIY hobbyists alike. The relay’s robust construction ensures reliable operation in harsh environments, from desert heat to sub‑zero winter conditions, thanks to its sealed contacts and corrosion‑resistant housing.

Because the relay includes a built‑in fuse, users can replace a blown fuse without searching for a separate component, streamlining maintenance and reducing downtime. The included harnesses are color‑coded (black for ground, red for VDC, white for trigger, blue for output) to simplify wiring diagrams and minimize errors during installation. Whether mounted in a passenger car, a heavy‑duty truck, or an off‑road vehicle, this relay delivers consistent performance and peace of mind.

FAQ

What vehicles are compatible with this 12V 30A relay?

The relay is designed for any 12 V automotive system that requires up to 30 A of continuous current. It works well in passenger cars, trucks, SUVs, RVs, and off‑road vehicles, especially for lighting, auxiliary pumps, and fan applications.

How do I replace the built‑in fuse?

To replace the fuse, first disconnect the power source. Locate the fuse socket on the harness, remove the old 30 A blade fuse, and insert a new fuse of the same rating. The harness is designed for easy access, and the replacement process takes only a few minutes.

Can this relay be used in a marine environment?

While the relay is sealed against moisture and corrosion, it is primarily rated for automotive use. For marine applications, we recommend additional waterproofing measures such as sealed enclosures or marine‑grade connectors.

What is the difference between the normally open (NO) and normally closed (NC) contacts?

This model features a normally open contact, meaning the circuit remains open until the relay coil is energized. This configuration is ideal for turning devices on only when a control signal is present, providing safety and energy efficiency.

Is technical support available if I encounter installation issues?

Yes. ONLINE LED STORE offers dedicated technical support via email and phone. Our engineers can help you interpret wiring diagrams, troubleshoot problems, and ensure the relay operates correctly in your specific vehicle setup.
