Buying Guide for Best 40 amp automotive relay

Types of automotive relays

Automotive relays come in a variety of different types and sizes, which can be used for a variety of applications. The most common types are 30 amp, 40 amp, 50 amp, and 70 amp. Each type has its own benefits and drawbacks depending on the application for which it is being used.

30 amp relays are the smallest size and are best suited for low-amperage jobs such as powering small electronics or accessories. They are also more affordable than the larger sizes.

40 amp relays are larger than 30 amps but still not as large as 50 or 70 amps. They offer more power than smaller relays while still being more affordable than larger ones. These are best suited for powering higher amperage items such as fans and headlights.

50 amp relays are the largest size typically available in automotive stores and can handle larger loads like high-powered lights or heavy-duty components such as winches or fuel pumps. They have higher power capabilities but also come at a higher cost than 40 amp relays.

70 amp relays are the largest size available and should only be used for extremely high-power applications such as starting engines or controlling large motors. These require special wiring and should be installed by a professional when possible, due to their large size and power requirements.
