How do I choose between a 4-pin and 5-pin automotive accessory power relay?

A 4-pin relay is designed for basic on/off switching of a single accessory like fog lights or a horn, while a 5-pin relay includes both normally open and normally closed terminals to alternate power between two different circuits.

Can this power relay be used to upgrade high-wattage horns or lighting on my car?

Yes, installing an accessory power relay directs battery current straight to the new high-draw horns or lamps while drawing minimal signal current through your steering wheel or dashboard switch, preventing switch burnout.

What is the coil power and resistance of this iRhapsody relay?

This iRhapsody relay features a coil power of 1.8W and a coil resistance of 80 ohms. This specification makes it more reliable than relays with 2.4W (60 ohms) or 4.8W (30 ohms) coil power.

What is the maximum current this 12V DC relay can handle?

The iRhapsody 12V DC relay has a maximum switching current capacity of 200A. It is designed for heavy-duty applications, but it's recommended to stay 10-15% below the rated value for optimal longevity and safety.

Is this continuous duty relay suitable for Indian weather conditions?

Yes, this relay operates reliably within a temperature range of -30°C to +80°C, making it suitable for the varying and often extreme temperatures experienced across India, including hot summers and cooler periods.

What are the terminal sizes for this 200A relay?

The round stud terminals for this 200A relay are M6 or 6mm, ensuring a secure connection for high-current automotive applications.

What happens if the load current exceeds the relay's rated value?

Exceeding the rated value of the relay's contacts can cause them to burn out, stick together, or even catch fire. Always ensure the load current does not surpass the relay's 200A limit.

About this item

The iRhapsody 12V DC 200A Continuous Duty Relay is engineered for demanding automotive applications, providing a reliable solution for split charging systems and high-power accessory circuits. Imported directly from authorized US retailers, this heavy-duty 4-pin SPST relay features a robust 200A current carrying capacity and a more reliable 1.8W coil power with 80 ohms resistance, outperforming many market alternatives. It operates within a wide temperature range of -30 to +80 degrees Celsius, ensuring consistent performance in diverse Indian climates.

This relay is designed for continuous duty, meaning it can remain energized for extended periods without overheating, crucial for applications like dual battery setups or powering auxiliary lighting. Its specifications include a nominal coil voltage of 12V DC, pickup voltage of 8V DC, and dropout voltage of 1.2V DC. The M6/6mm stud terminals ensure secure connections for high-current loads. Always match the coil voltage and contact current to your vehicle's circuit to prevent overload and ensure longevity.

For Indian vehicle owners, this imported relay offers a dependable upgrade for auxiliary systems. Ensure your vehicle's electrical system is compatible with a 12V DC supply. All customs duties and GST are included in the final price, with delivery via ExpressBox tracked shipping. This product is sourced from authorized US retailers and authorized brand partners, ensuring authenticity.

Key Features

Our coil power is 1.8W, and coil resistance is 80ohms. It is more reliable than 2.4W (60 ohms) and 4.8W (30 ohms) relays on the market
Large capacity, high current carrying capacity, heavy-duty make/break relay. But never go beyond its capabilities, try to stay 10 to 15% below what the rate is for
Rated voltage: 12vdc; Pickup voltage: 8v; Dropout voltage: 1.2v; The size of the round stud terminals: M6/6mm
Matching specifications: The coil voltage and contact current must be consistent with the circuit (for example, a 12V relay should be used with a 12V circuit)
Overload protection: The load current of the contacts must not exceed the rated value of the relay; otherwise, it may cause the contacts to burn out, stick together, or even catch fire

Why choose this product

Engineered for Continuous Duty

This iRhapsody relay is built for continuous duty, meaning it can be energized for extended periods without failure. Its robust construction and superior coil specifications (1.8W, 80 ohms) ensure it can handle demanding loads reliably, unlike standard relays that may overheat or fail under prolonged use. This makes it an excellent choice for critical automotive systems where consistent power is essential, offering peace of mind for long journeys or heavy-duty operations.

Ideal for Indian Automotive Upgrades

This relay is perfect for Indian car owners looking to add high-power accessories like auxiliary LED light bars, powerful electric horns, or dual battery systems for camping. Its 200A capacity and 12V DC compatibility make it a versatile component. While it's a high-performance part, it's not recommended for circuits exceeding its 200A rating or for use with 24V systems. For standard horn or lighting circuits without auxiliary power needs, a lower-amperage relay might suffice.

How to use

Verify Circuit Compatibility — Confirm your vehicle's electrical system is 12V DC. Ensure the intended load (e.g., auxiliary lights, winch) does not exceed the relay's 200A maximum switching current. Match the relay's coil voltage (12V DC) to your vehicle's power source.
Connect the Relay Terminals — Connect the 8mm stud terminals for the load circuit (usually the two larger terminals) to your accessory and the battery/power source. Connect the control circuit terminals (usually smaller pins) to your switch and the vehicle's 12V DC power source.
Install and Test — Mount the relay securely in an appropriate location, preferably in the engine bay or fuse box, ensuring it's protected from excessive moisture and vibration. Test the connected accessory to ensure the relay activates and deactivates correctly with your switch.
