Video Transcript for Curt Trailer Breakaway Kit - Kit with Charger - C52042 Review

Today, we're going to be taking a look at the Curt Push-To-Test Trailer Breakaway Kit with a Built-In Battery Charger. The breakaway system is going to activate your trailer's electric brakes if the trailer disconnects from the tow vehicle, which would bring your trailer to an eventual stop. Now, a breakaway system is require by law in most states for trailers that are equipped with electric brakes and have a gross trailer weight or towing weight of at least 3,000 pounds, so definitely check with your state's regulations. This unit's going to be a great option for you. It's going to feature a push-to-test battery case. It's going to offer fast and easy battery testing, all you got to do is press the large button right here, then one of three LED lights will pop on. Ours is green right now, so that means that we're fully charged.

If it was in the middle, it would shine orange, and that would mean charging. If it was on this side, it would show up as red, and that would mean low battery. It's also going to have the built-in charger that's going to automatically refuel the battery. Once the battery's fully charged, it's not going to overcharge it. It actually has a triple charge that maintains the voltage while you tow. Now, this is a side loading case, it's very easy to access from the side.

It's going to be made from a weather-resistant, polyethylene construction, which is going to protect the battery and charger from moisture and debris. It does come with the mounting hardware to get the case installed onto your trailer's frame, so right here you can see the battery. I do have it hooked up, that way you can see the LED lights on the tester side, but it's going to be a really nice 12-volt, gel cell battery that is included with this part number, and the battery capacity is going to be 5 amp hours. Now, this lid can be locked with a padlock. Padlocks are sold separately, but it can be locked to help deter theft. You're also going to get your breakaway switch, that's going to install in your trailer's frame, comes with the hardware to do that as well.

On this side, you're going to have the breakaway cable, this gets connected to the vehicle that's doing the towing. On this side, you're going to have two black wires. Now, one black wire goes to the breakaway battery's positive terminal, the other black wire gets spliced to the blue wire that leads to your trailer's electric brakes. The yellow wire on this unit gets spliced to the trailer's 12-volt auxiliary power lead, that's for your charger. Then the white wires are going to be your ground wire, it has a ring terminal on there, it's going to come with 2 self-tapping screws, one for the ground wire and one to get the breakaway switch mounted to the trailer frame. Let's going over a few dimensions real quick, starting with the box.

Measuring this direction from edge to edge, we're looking at a measurement of about 5 3/8 of an inch. Going this direction from outer edge to outer edge, we're looking at a measurement of about 5 1/2 inches. Now, these mounting holes, these are going to be separated on center going this way, take a look at that real quick. That's going to be 4 1/2 inches, and then, going this direction, they're separated on center by 3 inches. The switch, I'll just take a measurement of the base real quick, that's how much room it's going to take up on the frame, we're looking at about 4 1/4 of an inch, and then the width shows an inch and a half. That's going to do it for today's look at the Curt Push-To-Test Trailer Breakaway Kit with a Built-In Battery Charger.

Comments

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.

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

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

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

Ask the Experts about this Curt Trailer Breakaway Kit
Do you have a question about this Trailer Breakaway Kit?


  • 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...

  • 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...

  • 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...

  • 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.
