CURT 52042 is a complete side-load, push-to-test breakaway kit with a 12V/5A rechargeable battery and LED-ready charging indicator for trailers with one to three axles.
When towing, a breakaway kit is the battery-powered safety device that applies your trailer brakes automatically if the trailer separates from the tow vehicle. The CURT 52042 system combines a weather-resistant side-load battery case, a user-friendly push-to-test function, and a nylon breakaway switch so you can confirm readiness in seconds and recharge the battery on the go.
The integrated push-to-test button activates an LED readout that shows if the battery is charged, charging, or low, eliminating guesswork before you hitch up. Instead of removing the battery or using a voltmeter, one push gives a clear visual status so you can address power issues immediately.
The kit ships complete with a 12-volt 5-amp rechargeable battery, a built-in charger in the battery case, a nylon breakaway switch, and mounting hardware. All components are engineered to meet DOT standards for holding and breakaway situations on trailers with one to three axles.
The polymer battery case is molded to shed water and resist road debris, making it suitable for exposed mounting locations. The side-load design lets you access and remove the battery without dismounting the case, helping minimize wear and tear during routine checks and charging.
Charge the battery in the case using the built-in charger before storing the trailer; use the push-to-test button to verify charge level before every trip. Inspect the nylon switch, mounting hardware, and cable routing regularly for corrosion or damage and recharge the battery as needed to maintain readiness.
Who this kit is for: the CURT 52042 side-load push-to-test breakaway kit is designed for tow vehicle owners who want a simple, tested solution to meet DOT requirements on trailers with one to three axles. It's ideal for boat trailers, utility trailers, and small campers where fast pre-trip checks and on-trailer charging are valuable. If you prioritize quick diagnostics, weather resistance, and a compact, rechargeable battery system, this CURT kit is a practical addition to your towing setup.
Q: Will this kit work on trailers with electric brakes?
A: Yes. The CURT 52042 is designed for trailers equipped with electric brakes and supports one to three axles.
Q: How do I check the battery charge?
A: Press the push-to-test button on the case; LED lights will indicate charged, charging, or low battery.
