CURT Side-Load Push-to-Test Breakaway Kit 12V/5A for 1-3 Axle Trailers — LED Indicator, Weather-Resistant Case

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.

How does the push-to-test feature make pre-trip checks faster?

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.

• LED indicators: charged, charging, or low battery
• Instant confirmation with a single button press
• Reduces time spent on electrical pre-trip diagnostics

What components are included and how do they meet DOT requirements?

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.

• 12V, 5A rechargeable battery enclosed in side-load case
• Built-in battery charger for on-trailer charging convenience
• Nylon breakaway switch for reliable mechanical activation
• Mounting hardware for secure installation on most trailers

How durable and weather-resistant is the side-load battery case?

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.

• Weather-resistant plastic housing resists moisture and UV exposure
• Side-load access for quick battery removal and replacement
• Compact footprint to fit common trailer mounting points

How do I use and maintain the breakaway battery and switch?

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.

• Recharge in-place via built-in charger or remove battery to charge
• Press the test button weekly or before each trip to check LEDs
• Visually inspect switch and wiring for wear; replace if compromised

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.

If you prioritize quick diagnostics, weather resistance, and a compact, rechargeable battery system, this CURT kit is a practical addition to your towing setup.
