Product identity

The Meterk 12V 300A four-terminal solenoid relay is a nickel-plated SPST switch rated for a maximum transient current of 300 amps. It is built for 12-volt DC systems in golf carts, heavy-duty winches and marine applications.

Who this suits

Installers needing a water-resistant and dustproof relay with 5/16-24 contact studs and bracket mounting holes spaced 2-13/64 inches on centre. Buyers requiring continuous current above 150 amps or a duty cycle longer than five minutes with a 20-second cool-down should look elsewhere.

Installation checks

Verify that your system runs on 12VDC and that the coil resistance of 14 ohms matches the control circuit. Confirm the straight bracket with 5/16 by 19/32 inch holes fits the available mounting surface and that the four-terminal wiring layout matches the existing harness.

Questions about this item

What voltage supply does the 12 VDC solenoid coil require to operate?

The coil is rated for 12 VDC and draws 10.2 W at a resistance of 14 Ω.

Can the relay share a 12 V system with an existing 80 A fuse and wiring?

Yes, continuous working current is recommended under 150 A and typical use is around 80 A, so standard 12 V circuits are compatible.

How can I verify the relay is functioning correctly after installation?

Listen for the audible click when energised and measure voltage drop across the 5/16-24 contact studs; it should be minimal under load.
