Try to stay 10 to 15% below what the rate is for 12-volt 4-prong relay. Excellent water-repellent and dustproof ability, but not using it in water For the people whose relays are burning, please make sure you are making tight connections (especially on the load wires), read the specs on the item description, and ensure that the operating environment meets the safety requirements of the relay Be careful when inserting the relay into the socket. If you force it, you will bend the female connectors Thick 12 gauge wire for the load terminals. Easy to install, make sure you follow the wiring diagram.
