Automotive Relay
01
80Amp Auto relay HRA5
Product Features
High Current rating
The HRA5 relay is rated to switch loads up to 80A, making it ideal for applications requiring substantial current, including automotive motors, high-intensity lighting, and other heavy electrical devices.Typically designed for use with 12V or 24V DC systems, aligning with the standard voltage levels in most automotive applications. This ensures compatibility across various vehicle models.
HRA5 Common Applications
Automotive Lighting: Used to control high-beam headlights, fog lights, or other heavy-duty automotive lighting systems.
Electric Motors: Suitable for starting and operating electric windows, sunroofs, fans, and power seats.
Accessory Power: Commonly deployed in aftermarket applications to control additional electrical accessories fitted to vehicles.
Winches and Trailers: Used in controlling electric winches or towing equipment that demands high current.
Efficiency ,Reliability and Safety
Allows for efficient control of high-power devices without the need for heavy-duty switch gear, reducing overall weight and complexity in automotive design.
Robust construction and protective features enhance the reliability of high-power applications, leading to fewer failures and lower maintenance costs.
Proper usage of relays like the HRA5 can help protect the vehicle’s wiring harness by relieving electrical stress, reducing the risk of overheating and potential fire hazards.
Wire length can be customized
