Meterk 12VDC SPST Solenoid Relay

The Meterk 12VDC SPST solenoid relay is a four-terminal, nickel-plated contactor rated for 300A peak and 150A continuous current. It suits golf carts, winches, marine installations and other 12-volt DC circuits that need a single-pole, single-throw switching function.

Thermals and power draw in normal use

The coil draws 10.2W at 12VDC with a measured resistance of 14 ohms and uses 180-grade copper wire. The supplier notes a duty cycle of five seconds on followed by fifty minutes off when operating at high ampere levels, while typical working current is around 80A to avoid overheating.

Bundled hardware and what it changes

Copper 5/16-24 contact studs, 10-32 coil terminals and matching hex nuts with lock washers are included for secure, low-loss connections. The nickel-plated steel housing and potted coil interior provide water-resistant and dustproof sealing for harsh environments. Mounting holes on 2-13/64-inch centres allow direct bracket attachment.

Questions about this item

How do I mount the solenoid and wire the four terminals correctly?

Bolt the bracket using the 5/16 x 19/32 holes on 2-13/64 centres. Connect the two 5/16-24 copper studs to the high-current circuit and the two 10-32 steel terminals to the coil circuit; all nuts and lock washers are supplied.

What maintenance does the 12VDC SPST relay need over time?

The nickel-plated cover and potted coil resist water and dust, so no routine servicing is required. Inspect the 5/16-24 contact studs and 10-32 coil terminals periodically for corrosion or loose hardware.

How long can I run the relay at 150 A before it overheats?

Continuous rating is 150 A, but the maker advises a 5-second-on, 50-minute-off cycle at high current; typical working current is 80 A to avoid burning the coil.
