Built to keep your electric brakes engaged in an emergency, CURT trailer breakaway kits make a straightforward upgrade or replacement. Choose setups with a battery and switch, plus options with a built-in charger that maintains charge from your 12V trailer power and prevents overcharging. They work with electric-over-hydraulic systems and 1 to 3 axle electric brakes, and wiring can be run through a junction box; when relocating, fully disconnect the battery to avoid powering the brakes.
Yes. You can route the CURT kit into a junction box by landing each wire on the matching terminal. Check your plate's mounting hole layout against the box before drilling. If the lid hits when stacking two leads on the positive post, make a clean splice so one lead lands on the post and the lid closes properly. Seal wire exits to help keep water out.
Yes, CURT kits are designed for 1 to 3 axle trailers with electric brakes. If you supply 12V to the trailer connector in storage, the built-in charger will maintain the battery and helps prevent overcharging. For trailers that sit months at a time, confirm you have a constant 12V feed and test the push-to-test or indicator if equipped.
Yes, but completely disconnect the breakaway battery from the trailer so it cannot power the brakes. Remove the battery leads or the inline connection before moving the trailer. When reinstalling, mount the switch where the cable can pull straight, then reconnect power and test the breakaway function.
Connect Red to the battery, White to ground, Blue to the breakaway switch, and Black to the 12V power feed. Make these connections in a junction box if you prefer neat, secure terminations. Compare the included diagram to your wiring before powering up, since a misprinted diagram has caused confusion. Use a circuit tester to confirm 12V on the charge line.
Yes, CURT breakaway kits can power an electric over hydraulic system. Check that the kit's battery provides enough power to actuate your EOH actuator. Mount the breakaway switch on the tongue and wire it per the diagram. Before final crimping, verify the diagram matches your setup to avoid chasing wiring errors.
