High-Current 12V SPST Relay Pack

This pack contains two four-pin single-pole single-throw relays rated for 12 VDC nominal and up to 14 VDC maximum. Each unit switches up to 200 A using silver-alloy contacts for stable, high-power automotive, marine or split-charging circuits.

Build Integration and Included Hardware

The relays mount with standard four-pin footprints and ship with four 6.35 mm terminal wires, four 6 × 1/4 inch terminals, four 5 cm heat-shrink tubes and eight M6 copper gaskets. The kit supplies everything needed to wire the coil and load sides without sourcing separate connectors.

Thermal Range and Power Characteristics

Operating temperature spans from -40 °C to +90 °C, and the coil draws minimal current while the contacts handle continuous 200 A loads. Operate time is 15 ms and release time is 10 ms, so switching transients are brief and thermal stress stays low during normal duty cycles.

Questions about this item

Will the 200 A continuous rating hold up during a long winch pull?

The relay is rated for 200 A switching current at 12 VDC with a maximum applicable voltage of 14 V, and the silver-plated AgSnO12 contacts are designed for high-power duty cycles.

How hot does the coil get when the relay stays energised all day?

Operating temperature range is -40 to +90 °C; the flame-retardant housing and copper gaskets help dissipate heat during extended use.

What gauge wire and crimp tools do I need to connect the 6.35 mm terminals?

The kit includes 6.35 mm terminal wires, 6.35 mm ring terminals, M6 copper gaskets and 5 cm heat-shrink tubes for a complete installation.
