Heavy Duty 4-Pin Changeover Relay 150 Amp for General Purpose Agricultural Equipment

Description

When you’re dealing with high-current electrical loads on your farm equipment, an ordinary relay just won’t cut it. Standard automotive relays might handle 30-40 amps intermittently, but push them hard and they’ll leave you stranded. This 150-amp continuous duty solenoid is built for the brutal applications where ordinary relays fail. Whether you’re running hydraulic pumps, winches, or banks of work lights, this heavy-duty changeover relay handles the serious electrical loads your operation demands.

What You’re Getting

• The “continuous duty” rating is what sets this relay apart. While most solenoids are designed for momentary loads like starter motors, this unit can carry 150 amps all day long without overheating.
• Heavy silver-alloy contacts resist the arcing that destroys lesser relays, giving you years of reliable switching
• Robust coil design activates reliably even with voltage drops common in long wire runs. Weatherproof construction means it survives under-hood mounting where heat, moisture, and vibration challenge ordinary components.
• 4-pin design with normally open contacts that can be wired for changeover applications

Built for Real Farm Work

Whether you’re powering a heavy-duty winch pulling equipment from mud, running auxiliary hydraulic pumps on implements, or controlling banks of work lights for night operations, this relay delivers reliable switching power that won’t let you down. Common uses include master disconnect switches for equipment batteries, remote control of hydraulic power units, and any application where you need bulletproof reliability under tough conditions.

Made to Last

Unlike standard relays that overheat with prolonged use, this industrial-grade solenoid handles continuous high-current loads without breaking a sweat, keeping your equipment running when it matters most. The robust construction is designed specifically for the vibration, temperature swings, and harsh environment that farm equipment endures every day.

Installation Notes

Always use wire gauge appropriate for 150-amp loads – typically 2 AWG or larger for main connections. The 12-volt control circuit can use smaller gauge wire, but ensure good connections to guarantee reliable activation. Use quality ring terminals crimped and soldered for maximum reliability under high current loads. This relay works with any 12-volt system and can be mounted in standard electrical panels or custom installations.
