iRhapsody 12V 80/60A 5-Pin Automotive Relay Kit — 12-Pack with Heavy-Duty Pigtails, High-Current Rated

iRhapsody's 12V 80/60A 5-pin relay kit is a ready-to-install automotive switching solution built for high-current accessories and reliable long-term operation.

This kit includes twelve SPDT (5-pin) relays and heavy-duty pigtails designed to control up to 80A loads at 14V DC. Each relay is engineered with fast electrical response, robust insulation, and wire harnesses rated for durable conductivity and corrosion resistance, making it suitable for automotive, marine, off-road, and auxiliary electrical systems.

How does this relay kit handle high-current loads?

The relays are rated for continuous switching of up to 80A and a maximum switching power around 560W, which is suitable for many vehicle accessories like winches, lighting, and heavy pumps. Contact materials and internal design keep contact resistance low, reducing heat and voltage drop under load.

• NO contact rating: 80A at 14V DC for heavy circuits
• Contact resistance: ≤100 mΩ to minimize power loss
• Maximum switching power: ~560 W for high-demand devices
• Designed for repeated cycles: 100,000 electrical operations

Will these relays survive tough automotive conditions?

Yes — the relays are rated to operate across a broad temperature range and are tested for vibration and shock, so they remain reliable in mobile environments. Insulation and dielectric strengths are specified to resist arcing and maintain separation between coil and contacts under voltage stress.

• Operating temperature: −30°C to +80°C for varied climates
• Vibration resistance: 10–55 Hz, 1.5 mm amplitude for durability
• Shock tolerance: operational up to 10 g, damage limits up to 100 g
• Dielectric strength: 500 VAC between contacts, 750 VAC coil-to-contact

How fast and dependable are the relay responses?

These relays switch quickly and consistently: typical operate time is around 7 ms, with release in approximately 5 ms, supporting responsive control for safety and automation. Built for high mechanical life, they handle many cycles without significant wear when used within rated limits.

• Operate time: ~7 ms for prompt activation
• Release time: ~5 ms for quick disengagement
• Electrical life expectancy: ~100,000 operations at rated cycling
• Mechanical endurance: up to 10,000,000 lifetime cycles

What comes in the box and how do I wire it?

The package contains twelve 12V DC 80/60A SPDT relays with a heavy-duty pigtail harness for each relay. Wire color conventions follow common automotive standards for quick identification, and the harness conductors use tinned copper to reduce corrosion and improve conductivity.

• 12× 12V DC 5-pin (SPDT) relays per pack for fleet or multi-application use
• Pigtail harness: 12 AWG & 16 AWG tinned copper for durability
• Pin assignments: 30 red (power), 85 black (ground), 86 white (trigger), 87 blue (NO output), 87a yellow (NC output)
• Recommended practice: keep connections tight and load ratings 10–15% below relay capacity

Who is this for: This relay kit is for installers, hobbyists, and fleet maintainers who need robust, repeatable switching for high-current automotive or marine accessories. If you wire winches, auxiliary lighting, aftermarket pumps, or build custom electrical systems, the iRhapsody relays provide a practical balance of current capacity, environmental tolerance, and long life for heavy-duty applications.
