iRhapsody 12V 4-Pin Waterproof Automotive Relay Kit, 5-Pack — 80A Heavy-Gauge Wiring

This five-piece kit supplies reliable 12V DC relays engineered for high-current automotive accessories, lighting, and auxiliary systems. Each relay features a robust coil and low contact resistance for efficient switching, a waterproof housing to resist moisture and dust, and heavy-gauge wiring for load terminals aimed at minimizing voltage drop. Designed to withstand automotive vibration, shock, and a wide temperature range, these relays suit demanding vehicle environments when installed according to proper wiring diagrams.

How well does this relay handle high-current loads?

The iRhapsody relay is rated NO 80A at 14V DC and can switch up to 560W of power at rated conditions, making it suitable for many common automotive loads. Contact resistance is kept very low to reduce heating and voltage loss under load.

• Max switching current: 80A
• Max switching power: 560W
• Contact resistance: ≤100 mΩ (measured at 6VDC, 1A)
• Thick load wiring included for minimized voltage drop

Is this relay weatherproof and durable enough for vehicle use?

Each relay is built with a water-repellent, dustproof enclosure intended for exposed automotive locations, not for continuous immersion. The relay meets vibration and shock tolerance standards suitable for engine bays and off-road conditions.

• Water-repellent and dustproof housing (not submersible)
• Vibration resistance: 10–55Hz, 1.5mm amplitude
• Shock resistance: operational up to 10g, damage limits 100g
• Operating temperature range: −30°C to +80°C

What are the electrical and timing characteristics I should expect?

The coil is optimized for 12V DC operation with fast response times and robust insulation. It has low coil power consumption and a high maximum applied voltage tolerance to handle transient conditions when properly fused.

• Nominal coil voltage: 12V DC; coil power: 1.8W
• Coil resistance: 80 Ω; must-operate voltage: 6–8V DC
• Operate time: about 7 ms; release time: about 5 ms
• Dielectric strength: 500VAC between contacts, 750VAC between coil and contacts

How many relays and what accessories are included in the kit?

The package contains five complete 12VDC 80/60A 4-pin waterproof relays, ready for installation. The kit includes heavy-gauge wiring for the load terminals to simplify wiring and reduce losses; follow a wiring diagram for correct installation.

• 5 × 12VDC 4-pin waterproof relays per package
• Thick load wires attached for secure high-current connections
• Supports both positive and negative activation setups
• Recommended to fuse circuits and adhere to wiring diagrams

Who is this for: If you’re installing or upgrading automotive accessories such as auxiliary lights, fans, winches, or aftermarket electronics that demand reliable high-current switching, this iRhapsody relay kit is a practical choice. It’s aimed at mechanics, DIY vehicle owners, and fleet technicians who need a compact, weather-resistant 4-pin relay with fast switching, durable construction, and straightforward installation. Do not submerge the relay; use proper fusing and wiring practices to protect your vehicle’s electrical system.
