With a switching capacity of 70 amps at 12 volts, it is suitable for various electrical systems in cars. ### Protective diode for extra safety The relay is equipped with a flyback diode that suppresses voltage spikes. This protects sensitive electronic components from possible damage and ensures a longer lifespan for the electrical system. ### Compact and robust design Despite its high switching capacity, this relay has a compact size, comparable to standard mini relays. This makes it easy to integrate into existing installations without taking up much space. ### Specifications - **Voltage:** 12 volts - **Switching capacity:** 70 amps - **Connections:** 4-pin with flat plug terminals (2 x 6.3 mm and 2 x 9.5 mm) - **Dimensions:** Approximately 26 x 28 x 26 mm (LxWxH) without terminals and mounting tab ### Applications This relay is ideal for switching high current applications such as: - Lighting - Pumps - Fans - Other heavy electrical loads in cars ### Installation advice For correct operation, it is important to connect the positive terminal to pin 86 and ground to pin 85. This ensures the flyback diode functions properly and the system is optimally protected. ### Compatibility with relay sockets The relay can be mounted using a relay socket for a secure and safe installation. Make sure the relay socket is suitable for the dimensions and connections of this specific relay. ### Durability and reliability Made from high-quality materials, this relay offers a long lifespan and reliable performance, even under tough conditions. It is resistant to vibrations and temperature fluctuations, which is essential for automotive use. ### Important considerations When installing this relay, it is crucial to use the correct wiring and connections to ensure optimal performance and safety. Consult a professional for installation advice if necessary. ## Breadcrumbs - [Electrical](https://www.auto-service.be/en/electrical) - [Relay](https://www.auto-service.be/en/electrical/relay) - [High performance relays](https://www.auto-service.be/en/electrical/relay/high-performance-relays) ## Related products -
