This FalconSupply kit provides the Genuine OEM Trombetta 684-1251-012-02, an authentic PowerSeal DC Contactor engineered for high-demand, 100% continuous duty operation. This is not an aftermarket imitation; it is the factory-original component trusted by equipment manufacturers for its extreme reliability in harsh environments. Designed to safely manage a constant 150 Amp load, this IP67-rated waterproof solenoid is the definitive solution for critical 12-volt systems where failure is not an option. Its robust construction ensures maximum power transfer and total protection from moisture, dust, and vibration, making it the superior choice for mobile equipment, hydraulic systems, and heavy-duty vehicles. Detailed Technical Specifications Manufacturer Part Number: Genuine Trombetta 684-1251-012-02 Voltage Rating: 12 Volts DC Duty Cycle Rating: 100% Continuous Duty (Rated for 150 Amp constant load) Inrush Current Rating: 800 Amps Peak (Handles high motor startup draw) Environmental Sealing: IP67 Rated (Fully waterproof, dust-tight, and submersible) Coil Configuration: Non-Grounded / Isolated (Two 10-32 UNF studs for activation) High-Current Contact Studs: Two (2) 5/16"-24 UNEF Copper Studs Mounting: Integrated Flat L-Bracket (Flat-on-Side Mounting) Housing: High-Impact Plastic & Zinc Plated Steel Frame Direct Replacement & Primary Applications This component is a direct-fit replacement for various OEM systems. Its continuous-duty specification makes it ideal for, but not limited to, the following applications: Snow Plow Applications: Serves as the heavy-duty power contactor for various snow plow motor systems. Direct replacement for Hiniker (38350015), Pierce (63-5300), and SnowDogg (16160410). It is also a massive upgrade for Boss RT2 & RT3 Systems (HYD01633 / HYD08831) which traditionally use weaker intermittent relays. RV, Motorhome & Ford Chassis: A highly sought-after OEM upgrade for RV systems, acting as the main RV Battery Isolator Relay, chassis battery boost, or house charging solenoid. It works perfectly with an Isolator Relay Delay (IRD) to safely charge house batteries from the engine alternator, even when running heavy loads like a DC-to-AC inverter. It is a direct fit for the E450 battery isolator on Ford chassis motorhomes, the Winnebago Solis Pocket 36A, and Thor Chateau Class C models. Golf Carts & Industrial Equipment: Acts as a reliable, waterproof starter relay replacement for the Yamaha G29 Golf Cart. It is also highly recommended as a weatherproof upgrade for Woodmizer sawmills to replace failing horizontal relays in moisture-prone coil boxes. Heavy-Duty Hydraulic Applications: Ideal power relay for 12V DC hydraulic pump motors found on liftgates, dump trailers, winches, and leveling systems that require a continuous duty solenoid. What is Included in the Kit: (1) 684-1251-012 Solenoid Contactor (2) 5/16"-24 UNEF Nuts & Lock Washers (for high-current studs) (2) 10-32 UNF Nuts & Lock Washers (for coil terminal studs) (1) Dielectric Grease Packet (for weather resistance) (1) Installation Guide with Wiring Diagram & Safety Instructions Disclaimer: Installation should be performed by a qualified professional. Always verify part numbers against your specific application. Disconnect all electrical power by removing the negative battery cable before installation to prevent fire or component damage. Nuts must be tightened securely; loose connections can overheat and cause a fire, while over-tightening can break the studs.
