When your standard relay fails right in the middle of harvest or while you’re pulling equipment out of the mud, you realize why the pros use heavy-duty solenoids. This 150-amp continuous duty relay handles the brutal electrical loads that leave ordinary relays smoking. Whether you’re running winches, hydraulic pumps, or banks of work lights, this is the reliable workhorse that won’t quit when you need it most.
What You’re Getting
- 150-amp continuous duty rating that runs all day without overheating
- Heavy silver-alloy contacts that resist arcing and pitting from high current
- Weatherproof construction built to survive engine compartment conditions
- 12-volt coil that activates reliably even with voltage drops in long wire runs
- Multiple terminal configurations for versatile switching applications
Built for Real Farm Work
This relay excels where standard automotive relays fail—controlling winches pulling stuck equipment, powering auxiliary hydraulic systems on implements, switching high-amp alternator circuits, and managing resistance heating elements. It’s also perfect for master disconnect switches and remote hydraulic power unit control where reliability can’t be compromised.
Made to Last
The continuous duty rating means this relay can carry 150 amps indefinitely without the overheating problems that plague standard relays. The robust coil design and heavy-duty contacts are built for the heat, moisture, and vibration of farm equipment where failure isn’t an option.
Installation Notes
Use 2 AWG or larger wire for the main 150-amp connections, and mount the relay on a heat-dissipating surface away from exhaust components. Quality ring terminals crimped and soldered ensure reliable connections under high current loads. A flyback diode across the coil terminals prevents voltage spikes when switching inductive loads like motors and solenoids.
