Amid the Covid 19 craziness, I contacted eTrailers to check on an order I had placed and discovered it was back ordered until July. Theresa assisted me in cancelling that order and finding the parts I needed for my trailer in short order. I received the parts promptly and cannot give enough praise to Theresa, she’s an asset to the eTrailer family. 784999

Arrived quicker than expected. Seems to be high quality. Have not had time to install, so I cannot address the difficulty of installation or the performance. 580658

Very good product. Don’t want to see a trailer with thin enough steel that the mounting screws would actually work. Did have a bit of a hard time mounting since the bolt spacing was pretty wide, but got it to work. Kit is complete, works very well, and was relatively simple to install. Recommend it for the money. 642026

Not well. I dont know if I wired it wrong or what, but the battery died. Everything checks out ok with a multimeter except the dead battery.

If the vehicle 7-way that you are using this with does not have a powered 12-volt connection to help maintain the battery then that may be the issue. If not then check out the installation instructions and refer to page 2 for additional info.

Replaced a outside rail unit on my Trailex enclosed (1999) with this unit, but moved it inside by winch mount to better protect from elements. 1 year in, start of new towing season, still working as designed (brake engage), charging off of tow vehicle 12v power from 7-pin cable source. Would buy again to replace a dead battery, to all new accessories, not a place to scrimp. 258608

Ask the Experts about this Curt Trailer Breakaway Kit

  • Can Trailer Breakaway Kit Be Installed Into Junction Box for Cleaner Connections
    Sure, if you want to install the breakaway kit through the junction box, you would just need to make the connections that would normally run to the wiring harness, into the respective terminals inside the junction box. While we don't have a video to show how this is done, you can use the attached diagram that I've put together for you. For a junction box, I recommend part # 38656 and for a breakaway kit, I recommend the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger...

  • How To Wire the Curt Push-To-Test Trailer Breakaway Kit
    In regards to the Curt Push-To-Test Trailer Breakaway Kit part # C52042, the blue wire on the breakaway switch will be run to the brake output circuit and the black wire to a constant 12 volt power source. The blue wire on the battery box will also will be run brake output circuit, the red wire to a 12 volt power source, and the white wire to a ground.

  • Where to Attach Cable for Curt Push-To-Test Trailer Breakaway Kit
    The most common method for attaching the cable for a breakaway kit like the Curt Push-To-Test # C52042 that you referenced is feeding it through the safety chain loop on the trailer hitch. The warning message that you mentioned on the instructions manual caught me a little off guard so I called my contact at Curt and he actually said that "mounting hooks" in that statement refer to the hooks on the safety chains themselves. He said that the cable can absolutely be connected to the tow...

  • How To Wire the Curt Push-To-Test Trailer Breakaway Kit C52042
    In regards to the Curt Push-To-Test Trailer Breakaway Kit part # C52042 (52042), the blue wire on the breakaway switch will be run to the brake output circuit and the black wire to a constant 12 volt power source. The blue wire on the battery box will also will be run brake output circuit, the red wire to a 12 volt power source, and the white wire to a ground.

  • Could One Trailer Breakaway Kit be Used on Several Fifth Wheel Trailers
    Breakaway kits aren't really designed to move from trailer to trailer easily. They are designed for a permanent install. Since nearly all areas will require a breakaway kit to be installed on the trailer the best solution would be to install a breakaway kit like the part # C52042 on all of the trailers. It'll also save you a lot of time trying to swap the kits each time you have to tow a different vehicle.

  • Comparing Trailer Breakaway Switch Kits
    Some different brand names of trailer breakaway kits do originate from a common source, and this is also true for items like jacks, landing gear and steps. There really is not a lot to distinguish one from another, since their component parts are virtually identical: a battery, a box, a charger and a switch. The one part that can make a difference is the battery itself. A higher output battery can power brakes on more axles. Hopkins Engager Trailer BreakAway Kit # 20400 can handle 1 or...

  • Is There a Curt Soft Trac Breakaway Kit that Has Battery Charge Indicator
    If you are looking for a similar trailer breakaway kit that has a built in charger and tester we have the Curt part # C52042 which will show you when it's charging and charged but the part # C52040 that you referenced does not have this feature.

  • Does Charging Battery of Curt Breakaway Kit # C52042 Take a Long Time
    To charge a battery through the 12 volt accessory circuit of a vehicle and trailer wiring does take some time. If the battery was in a pretty low state of discharge it would not surprise me that it's still charging. If you wanted to charge the battery quickly you'd need a charger that plugs into a wall outlet like the part # CTEK56353.

  • Best Breakaway Kit with Push To Test Feature for Triple Axle Trailer
    I do have an option for you but the Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger part # 20099 is only rated for use on single and tandem axle trailers. For a breakaway kit that is rated for use on triple axle trailers you will want to use the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # C52042. The Curt breakaway kit as the title suggests also has a built-in push to test feature as well as a side load battery box just like the Hopkins...

  • How To Move A Trailer With A Dead Breakaway Battery
    On most breakaway kits such as the Hopkins Brake Master part # HM20001, you will not need to cut or splice any of the wires to move the trailer with a dead battery. If your power supply is not active, then the only effect is that the breakaway system will not send power to your trailer's brakes in a breakaway situation thus allowing for free movement of the trailer. Even if the battery is dead, the brake controller will still allow you to activate your trailer's brakes To prevent further...
