40/60 Amp Relay Only

The DERALE 40/60 Amp Relay Only (SKU: DER16764) is a heavy-duty electrical relay designed for automotive auxiliary systems requiring robust switching capability. This relay functions as the control center for high-amperage circuits, enabling reliable on/off operation of electric fans, fuel pumps, and other power-hungry 12V components. Whether upgrading cooling systems on custom builds or replacing a failed relay in an existing setup, this universal relay delivers the dependable performance that serious enthusiasts and technicians demand.

This 40/60 amp relay operates on 12-volt DC systems and handles both the pull-in draw and sustained current load typical of demanding electrical circuits. The dual-amperage rating (40 amps pull-in, 60 amps holding) ensures the relay initiates contact closure reliably even under low-voltage conditions, then sustains the full circuit load without chatter or dropout. Its compact footprint—measuring just 2.75 x 1.4 x 3.6 inches—fits seamlessly into engine bays and electrical enclosures, while the lightweight 0.11 lbs design adds virtually no weight penalty to your build. The relay-only configuration allows integration into custom wiring harnesses and control systems where OEM relay housings may not fit or function as required.

Engine builders, restoration shops, and performance enthusiasts rely on this relay for auxiliary fan circuits, nitrous oxide purge systems, and fuel system upgrades where standard automotive relays lack sufficient capacity. Its universal design works across domestic and import platforms, from classic muscle cars to modern performance builds. Installation requires basic wiring knowledge—connect the control signal to the coil terminals and route the high-amperage load through the normally-open contact points. For those designing custom 12V electrical systems or replacing worn relays in complex builds, the DERALE 40/60 Amp Relay Only provides proven switching reliability in a compact, affordable package.
