How to Select a Trailer Hitch
Breakaway hardware sits on the trailer. Hitch class selection on the tow vehicle is a different shopping trip, but both matter before a Canadian tow day.
Watch on YouTubeTrailer Breakaway Battery Tips (Canada)
A trailer breakaway switch only helps if the trailer battery behind it is charged and ready. In Canada that usually means checking the breakaway battery before a trip, confirming the cable reaches the tow vehicle, and testing the system so the trailer brakes can still apply if the coupler separates. This page keeps the advice practical, links the breakaway-cable guide, brake-controller, and first-tow checklist, and points to live CURT breakaway and battery SKUs that are stocked on this store. We will not invent legal cutoffs or claim any battery age rule as law.

Watch these CURT videos first
All four videos are from the official CURT YouTube channel (@curtmfg). Use them for hitch class, install habits, wiring basics, and ball-mount height so the tow vehicle side of the trip stays as honest as the breakaway battery on the trailer tongue.

Trailer Hitch Installation Techniques
Hardware that sees road salt still needs a recheck habit after the first trips of the season, breakaway mounts and battery cases included.

Trailer lights and brake-controller wiring still need a plug-test habit. A dead breakaway battery and a lighting fault are different problems.

Level the trailer with the right ball mount so the tongue sits honest before you trust breakaway cable reach and battery readiness.
Watch on YouTubeWhat the breakaway battery is for
Electric trailer brakes need power if the trailer separates from the tow vehicle. The breakaway switch pulls open when the cable stretches, and the trailer battery is what feeds those brakes for a short emergency window. A switch with a dead battery is mostly theatre. Charge the battery on a schedule you can stick to, especially after winter storage and after long sits in a cold Canadian shed.
This page is not a provincial law brief. Rules for when trailer brakes and breakaway systems are required vary by trailer weight, axle count, and where you drive. Read your trailer plate, owner paperwork, and local rules rather than treating any store page as a legal cutoff.
Parts-counter habits before you leave the driveway
| Topic | What we tell shoppers |
|---|---|
| Charge first | Confirm the breakaway battery is charged before a trip. A charger on the shelf beats a surprise dead cell at the ramp. |
| Test the switch | Many kits include a push-to-test style check. Use the live kit instructions. Feel or hear brake apply when the switch is pulled or tested, then reset for the road. |
| Cable reach | The lanyard must reach the tow vehicle without dragging. Open the breakaway cable guide for attach habits. |
| Case and weather | A watertight or covered battery case helps in salted Canadian weather. Keep terminals clean and dry. |
| Brake controller | The tow vehicle still needs a working brake controller for normal stops. Open do I need a brake controller. |
| First tow day | Lights, chains, coupler, tires, and breakaway all belong on the same walk-around. Open the first tow checklist. |
| No invented cutoffs | We will not invent legal cutoffs for battery age, trailer weight, or provincial brake rules. Confirm local requirements yourself. |
| Kit versus parts | Some shoppers want a complete breakaway kit. Others only need a replacement battery, switch, or lanyard. Match the live SKU to the job on the tongue. |

How this sits beside brake controllers
Breakaway protects the trailer if it separates. A brake controller on the tow vehicle still handles everyday stops. Wireless and under-dash CURT controllers remain a tow-vehicle shopping trip, not a substitute for a charged breakaway battery on the trailer tongue. If you are choosing a controller, start with the brake-controller guide and confirm harness fit for your truck or SUV.
