It comes in a compact size, measuring just 35mm x 22mm x 12mm (LxWxH), making it suitable for various installation scenarios. The relay's contacts are rated for a maximum current of 5 Amps and a voltage of 12 Volts DC, ensuring reliable operation even under heavy loads.

The HR-CR313DC012's coil requires a 12VDC input to activate the relay contacts. It has a contact rating of 250VAC/50Hz, allowing it to switch AC loads as well, making it a versatile solution for various applications. The relay comes with a built-in diode to prevent coil damage when an inductive load is switched off.

The HR-CR313DC012 is constructed with high-quality materials, ensuring long-lasting performance. It features a gold-plated contact surface to reduce contact resistance and ensure a secure connection. The relay's housing is made of a robust, thermally stable material that can withstand harsh environments.

Installation of the HR-CR313DC012 is straightforward. It comes with a screw terminal block that allows easy wiring of the input, coil, and load connections. The relay also features a clear and concise labeling system for the terminals, making it easier for users to identify the correct wiring configurations.

In summary, the Hankuk HR-CR3 HR-CR313DC012 is a high-performance, versatile, and reliable 12VDC 5A relay. Its compact size, robust construction, and easy installation make it an ideal solution for various switching applications, whether for DC or AC loads.

The Hankuk HR-CR3 HR-CR313DC012 relay is a 12VDC, 5A relay often used in various automotive applications. Let's discuss its pros and cons to help you make an informed decision.

1. High Current Capacity: This relay can handle a maximum current of 5 Amperes, making it suitable for handling heavy loads.

2. Wide Operating Voltage Range: The operating voltage range is between 8VDC and 32VDC, providing flexibility for various battery systems.

3. Compact Size: With dimensions of 44mm x 31mm x 18mm, it is a space-saving option for applications where size is a concern.

4. Robust Construction: The relay features a rugged design with an epoxy resin coating, ensuring durability and protection against harsh environmental conditions.

5. Quiet Operation: This relay operates quietly, which is essential in applications where minimal noise is required.

1. Limited Switching Frequency: The maximum switching frequency is relatively low (up to 30 times per second), which might not be suitable for high-speed applications.

2. Manual Reset: In case of an overload, the relay requires manual resetting, which can be time-consuming in certain applications.

3. Lack of Protection: The relay does not have built-in protection features, such as over-voltage or over-current protection, which may necessitate additional components.

The Hankuk HR-CR3 HR-CR313DC012 relay is a reliable and robust option for handling moderate current loads in various automotive applications. Its compact size, wide operating voltage range, and quiet operation make it an attractive choice. However, its limited switching frequency and manual reset feature might not be ideal for high-speed or critical applications. If you need a relay for heavy-duty applications with frequent switching, you might want to consider a relay with a higher switching frequency and built-in protection features.

If you are looking for a reliable and compact 12VDC, 5A relay for general automotive applications, the Hankuk HR-CR3 HR-CR313DC012 relay is an excellent choice. However, if you require a relay with a higher switching frequency, built-in protection features, or manual reset is not a concern, there are other options available in the market that may better suit your specific application. Always consider your unique requirements when choosing a relay to ensure optimal performance and reliability.
