The purpose of a relay is to automate this power to switch electrical circuits on and off at particular times. Car qook automotive dc 12v 12 volt 30a amp spdt wiring power relay. Variety of 12 volt solenoid wiring diagram. The real benefit behind a relay is more than automation. Low Voltage & Automotive Circuit Protection For fusing DC circuits with significant voltage (50 to 700VDC), a semiconductor fuse is generally specified. For 12VDC, interrupting capacity is generally not an issue because low voltage systems have so much series resistance, that the current rarely exceeds about 2kA, and 12VDC is insufficient voltage to maintain an arc across open contacts.
