Fastronix Solutions Weatherproof 50/30A Automotive Relay & Locking Socket Kit — Sealed, Vibration‑Resistant

Fastronix 50/30 Amp Weatherproof Automotive Relay and Socket Kit is a sealed, vibration-resistant relay system with a heavy-duty socket and wiring for powering off-road lights and accessories.

This weatherproof relay and socket kit from Fastronix Solutions combines a dual-rated relay (50A normally open, 30A normally closed) with a locking OEM-style socket, pre-wired copper leads, and a mounting tab to simplify robust automotive installations. Designed for environments with moisture, dust, and vibration, the kit gives a reliable switching solution that protects contacts and wiring while keeping installation straightforward for cars, trucks, ATVs, and utility vehicles.

How does this relay protect my electrical system from the elements?

The relay is fully sealed and vibration resistant, minimizing exposure to water, dirt, and mechanical stress. Sealing helps prevent corrosion on the contacts and preserves switching performance over time.

• IP-style weatherproof enclosure resists moisture and dust infiltration
• Vibration-resistant design reduces contact wear in rough terrain
• OEM locking-style socket helps secure the relay under hood or on racks

What wiring and current ratings should I expect for accessories?

The relay is rated to switch 50 amps on the normally open circuit and 30 amps on the normally closed circuit, covering most high-current lighting and accessory loads. The supplied socket includes heavy copper leads sized for safe conductance and durable connections.

• 50A normally open capacity for high-draw accessories like LED bars
• 30A normally closed option for alternate circuit needs
• Three 12 AWG primary copper leads and two 18 AWG coil leads for secure, minimal-voltage-drop wiring

How easy is installation for a DIY mechanic or shop technician?

Installation is designed to be straightforward: the kit includes a pre-wired socket with 12" leads, a wiring diagram, and a mounting tab for quick attachment. The OEM locking-style socket and color-coded leads reduce guesswork, so you can mount, wire, and test the relay in minimal time.

• 12" copper wire leads give working length without extension
• Included wiring diagram clarifies coil and load connections
• Mounting tab lets you secure the relay close to the load or fuse block

Which applications are best suited for this relay kit?

This kit is ideal for switching high-current automotive accessories where environmental protection matters. Typical uses include off-road lighting, winches, auxiliary power circuits, and any accessory that benefits from a durable, sealed relay and pre-wired socket.

• Off-road light bars and spotlights requiring up to 50A switching
• Accessory circuits on trucks, ATVs, UTVs, and boats (where weatherproofing helps)
• Aftermarket installs where vibration and exposure could otherwise cause failures

Who is this for: The Fastronix 50/30 Amp Weatherproof Relay and Socket Kit is aimed at DIY enthusiasts, professional installers, and fleet technicians who need a compact, sealed switching solution for high-current accessories. If you install off-road lighting, auxiliary power devices, or any accessory exposed to moisture and vibration, this kit provides heavy-duty switching, clear wiring, and the protection necessary for reliable operation.
