  • CURT

The battery case in this breakaway kit can clamp around your trailer frame or jack post. Kit brings your single-, double-, or triple-axle trailer to a stop should it become disconnected.


Features:

  • Makes sure your trailer safely stops if it ever separates from your vehicle
    • When the pin gets pulled from the switch, a signal is shot back to your trailer brakes to activate
  • Clamps around your trailer's frame or jack post
    • Top-loading case provides easy access to battery from above
  • Breakaway switch installs on your trailer's frame with self-tapping screws (sold separately)
  • Protects battery from rain and debris with durable, plastic case
    • Lid can be secured with padlock (sold separately) to deter battery theft
  • Includes battery, battery box, breakaway switch, wiring, installation hardware, and breakaway cable
  • Department of Transportation (DOT) compliant


Specs:

  • Application: single-, tandem-, and triple-axle trailers with electric brakes
  • Battery:
    • Voltage: 12V
    • Type: sealed lead acid
    • Capacity: 5 amp-hours
  • Breakaway cable length: 44"
  • Breakaway switch:
    • Dimensions: 4-3/8" long x 1-1/2" wide
    • Lead wire length: 16-1/2"
  • Battery box dimensions: 5" long x 3-1/4" wide x 3-7/8" tall
  • Trailer jack mounting hold diameter: 3"
  • 1-Year limited warranty


Note: A breakaway system is required by law in most states for trailers that are equipped with electric brakes and have a GTW of at least 3,000 lbs.


Quick Tips:

  • When you store your trailer, be sure to keep the pin plugged into the breakaway switch. If the pin's removed for an extended period of time, dirt and moisture can get into the switch and cause corrosion that could keep it from activating when you need it.
  • A breakaway system needs to be able to apply the trailer brakes fully for at least 15 minutes. In general, the heavier your trailer, the higher amperage battery you'll need for the breakaway.

Very well satisfied once again with etrailer.com and the products. Always recommend etrailer.com to other people.

As advertised. Good instructions, and easy to install. I would have liked more options for mounting the battery, but it fit around the tongue jack with no problems.



by:

Installation was easy and worked great.



by:

Install went great, battery ships at about 8vdc but will trickle charge with the included charger (off the truck when trailer connected). What I liked was that the charger and battery are pre wired. It also comes with an extra charger in the box. Kudos to curt. Thanks.

Everything was fantastic.

I wanted to reach out to you in regards to your review on the Curt breakaway battery. You mentioned that you have not used the kit. I wanted to ask if there was something about the kit that has made you not want to use it or if you just have not had the need to install it yet?

It turns out that pulling CDL rated fifth wheels requires I use a full size battery for the braking system. I never really needed it in the first place. Those are rated to stop only smaller bumper pull type.

Bolted up fine and worked well during one season so far.

product is not installed yet. shipping was fast but you lost a sale because of price
matching . I would have preferred buying it from you but no one would call me back.
jeff was more than helpful getting me the right product . I bought the pump elsewhere due to a 40 dollar price difference

  • Does the Brake Output Wire Get Attached to a 12 Volt Trailer Battery
    In order to rewire your trailer, I strongly recommend you use the Trailer Wiring 7-Way Upgrade Kit part # HS381-9000 with the Bonded 4 Wire part # 16-4B-1. This is going to ensure you have all the correct wire gauge and the junction box makes for a clean install as well as an easy way to troubleshoot if you ever have issues. In regards to the brake output wire part # 10-1-1, this will receive power from the tow vehicle's brake controller via the 7-way, not a battery during normal braking....

  • Does The Curt Soft Trac II Trailer Breakaway Kit Come With A Battery Charger
    Breakaway batteries are typically just wired to the 12v power wire in the trailer's junction box so that the battery can charge while connected to the tow vehicle. The Curt Soft Trac II Trailer Breakaway Kit # C52026 comes with a ground wire already connected to the battery. You can run this directly to the frame with a ring terminal and self-tapping screw. For the power wire you can use some 14ga wire # DW02408-1 and just run it to the junction box on the trailer and connect it to the...

  • Clamp Size for the Curt Breakaway Battery Kit part # C52026
    The clamp of the Curt Breakaway kit part # C52026 that you referenced is 3 inches wide and 1-1/2 inches tall. It would work well on a 2 inch wide frame rail.

  • Trailer Breakaway System Battery Requirements for 5th Wheel
    A trailer breakaway system must have a dedicated battery on the trailer. If it did not have its own battery the breakaway system would not operate if the trailer connector disconnected from the vehicle. A dedicated breakaway battery is required so that an uncoupled trailer's brakes will activate to bring it to a stop, but a second backup battery on the trailer is not required. I linked our main page for trailer breakaway kits. We offer basic kits like # C52026 and kits with a built-in...

  • Does a Breakaway System Need To Have Its Own Battery
    The breakaway system actually must be attached to its own separate battery by law in most states. Therefore, I cannot recommend that you use a seperate, auxiliary battery on the trailer or the vehicle for that matter for the breakaway switch. The most cost effective breakaway system we have for you is the Curt Soft Trac II Trailer Breakaway Kit part # C52026. I have attached a photo for you to show how it will need to be wired.

  • Adding Trailer Brakes to a 3.5K Dexter EZ Lube Axle and Brake Control/7-Way on 2016 Subaru Outback
    The brakes you have chosen, # 23-468-469, are compatible with the hub and drum assembly # 84556UC3-EZ and those assemblies will fit the Dexter 3.5K EZ Lube axle. The thing about this hub and drum is the bolt pattern. It has a 5 on 5 bolt pattern which is not very common anymore. I would verify that is indeed the pattern you need by using our help article on measuring for bolt pattern which I have linked for you. If you have a different bolt pattern let me know and I can make some recommendations. Wiring...
