Relay Switch Kit for Dump Truck Tarp Systems (Complete)

The Complete Relay Switch Kit for Dump Truck Tarp Systems

When it comes to operating heavy-duty electric tarp systems on dump trucks and trailers, reliable electrical control is not just a convenience—it is a necessity. The Relay Switch Kit - Complete Kit (SKU: 25-P-700R) from DeBrovys is engineered to provide safe, consistent, and weatherproof power to your tarp motor. Designed specifically for the rigorous demands of the commercial trucking and waste industries, this complete kit replaces standard, vulnerable switches with a robust, sealed relay module system.

Electric tarp motors require significant amperage to efficiently wind and unwind heavy mesh or vinyl tarps over heaped loads. Traditional rotary or toggle switches often fail prematurely under this heavy load because all the current passes directly through the switch in the cab. The 25-P-700R relay system solves this critical issue by keeping the high-amperage power outside the cab, utilizing a low-amperage rocker switch to trigger the heavy-duty dual relay blocks. This ensures maximum safety, significantly longer component life, and reliable operation in any weather condition.

What is Included in the Complete Relay Switch Kit?

The DeBrovys Relay Switch Kit comes with everything required for a complete, professional installation. We have bundled all the necessary components so you do not have to waste time sourcing individual parts. This kit is designed to get your electric tarp system back up and running with minimal downtime and maximum efficiency.

Inside the package, you will find the heavy-duty weatherproof relay module (featuring two sealed relay blocks mounted on a durable circuitry deck), which acts as the heart of the system. The kit also includes a sleek, universal rocker-style switch for the cab, a weatherproof protective cover for the relay terminals, an auto-reset circuit breaker, a heavy-duty tri-wire harness (typically 15 to 25 feet in length), and a complete assortment of terminal rings, mounting plates, and hardware.

Why Upgrade to a Weatherproof Relay System?

Many dump truck operators start with a basic rotary or toggle switch, only to find themselves replacing it every season due to burned-out contacts or water intrusion. Upgrading to the Relay Switch Kit offers several distinct advantages that save you money and frustration over the long haul.

First and foremost is weatherproofing. The relay module is fully sealed against moisture, dust, road salt, and debris. This means you can mount it externally on the truck frame or near the tarp motor without worrying about corrosion destroying the internal contacts. Second is electrical safety. By routing the heavy 50+ amp current directly from the battery to the relay module and then to the motor, you keep dangerous high-amperage wiring out of the truck cab. The driver only interacts with a safe, low-voltage rocker switch. If you frequently haul corrosive materials under your Waste Industry Tarps, this sealed system is an absolute necessity.

Universal Compatibility for Major Tarp Brands

The 25-P-700R Relay Kit is engineered for universal compatibility. It is designed to work flawlessly with standard 12-volt DC electric tarp motors used across the commercial trucking industry. Whether you are running a front-to-rear flip tarp on a single-axle dump or a heavy-duty system on a long roll-off trailer, this relay kit provides the necessary reversing power.

This kit serves as a direct replacement or upgrade for systems manufactured by Roll-Rite, Donovan, Aero Industries, US Tarp, Buyers Products, Mountain Tarp, Pull Tarp, and Tarping Systems Inc. (TSI). It replaces common parts such as the Buyers Products 5541020. No matter what brand of Truck Tarp Systems you operate, the relay module will integrate seamlessly.

Built to meet the rigorous demands of commercial fleet operators, this relay kit delivers uncompromising electrical performance. Below are the core technical specifications for the Relay Switch Kit - Complete Kit:

Installation and Wiring Best Practices

Installing the Relay Switch Kit is a straightforward process, but proper wiring is essential for optimal performance. The relay module itself should be mounted securely to the truck frame or bulkhead, ideally as close to the tarp motor or battery as practical to minimize the length of heavy-gauge power cables. The included weatherproof cover must be installed over the terminals to ensure the system remains sealed against the elements.

The included tri-wire harness connects the relay module to the rocker switch inside the cab. Because the rocker switch only handles a low-amperage trigger signal, the wiring routing into the cab is much easier and safer than running thick battery cables through the firewall. Always ensure the included auto-reset circuit breaker is installed inline on the main power feed to protect the motor. If you are doing a complete system overhaul, consider pairing this electrical upgrade with one of our durable Replacement Tarps to ensure your entire load covering system is in top condition.

Built Tough for the Commercial Trucking Industry

At DeBrovys, we understand that every minute your truck is down for repairs is money lost. That is why we stock premium, industrial-grade components like the Relay Switch Kit. The dual relay design ensures reliable power switching and withstands extreme vibration, temperature fluctuations, and environmental exposure.

Do not let a cheap, unsealed switch leave your driver stranded with an uncovered load. Upgrade your electric tarp system with the 25-P-700R kit and experience the peace of mind that comes with reliable, weatherproof power control. Whether you are hauling asphalt, gravel, or agricultural products under our heavy-duty Industrial Fabrics, the relay kit ensures your load is secured quickly and safely, every time.
