Description

Breakaway Kit Incl 5ah Battery | Switch | 12v/5A Battery | Rubber Boot

The Breakaway Trailer Brake Kit is mandatory for all trailers over 2000 kg GTM. Should the tow vehicle and trailer separate accidentally, the trailer brakes are engaged at full power for a minimum of 15 minutes.

The breakaway system provides a total solution to the Australian Design Rule requirements.

Important Note: Lanyards must be shortened during installation. Click this link for more information.

Caravan and Trailer on-board Battery Kit

Note; it is important to note that there is no requirement for an independent, designated or separate breakaway battery system.

In other words, your onboard 12v battery in your caravan or camper may be used as a breakaway battery provided it can apply 12vdc to your electric brakes.

Further, the onboard caravan battery will be larger than the minimum requirement and have the same or larger capacity than the smaller unit.

The breakaway switch is designed to operate electric brakes for 15 minutes in cases where the trailer was detached from the vehicle when travelling.

Additionally, included in the price is a rubber boot that fits over the breakaway switch. The rubber boot greatly helps prevent water ingress.

Furthermore, whenever a Trailer is presented for inspection, the towing vehicle must be equipped with a compatible charging system that is connected to the trailers breakaway battery.

Finally, a label must be affixed to all-electric barked trailers stating that any tow vehicle must be equipped with an acceptable charging/warning circuit.

Breakaway kit testing.

  • Connect the wires to the terminals. In a fully charged state, a green light will glow
  • Remove the pin and notice a sound coming from your magnets
  • You may hear a hum or a tick as the electric magnet sticks to the inside of the drum
  • When energised, check the voltage at the battery
  • If the voltage is under 12 volts then either the battery is putting out less than 12v, or you have a voltage loss
  • If voltage loss exists, increase the size of the cable to the brakes to 4mm or 5mm.

Increasing the size of the cable removes voltage loss and restores voltage to 12vdc.

Wiring Diagram for Breakaway Kit.

Breakaway Trailer Brake Kit for Hydrastar

Electric / Hydraulic controllers use a 17 Amp Hour battery because the hydraulic motor uses more power than an electric magnet.

Standard 1200 psi and 1600psi Hydrastar actuators use a 5ah Breakaway Kit battery,

Caravan and Trailer breakaway kits article can be found here.

Breakaway replacement wire and pin

Replacement wire and pins are now available. Broken pins occur during testing can now be replaced without purchasing the entire breakaway switch.

The plastic-coated wire is 1.1 meters long and requires adjusting to the correct pull length.

5A – 12V Replacement Battery to suit Breakaway Kit.

5A means 5 amps or 5 x 12 = 60 watts for one hour

The battery should be large enough to power 4 magnets @ 3.2Amp each for 15 minute

How do I tell when the battery requires replacement?

Your breakaway battery will require replacement when you cannot get a green light on your control panel.

In Australia, the test button must indicate

  • Full Battery Power Available.
  • Battery Charging.
  • Battery flat

As opposed to America where there is no requirement for test lights.

If your battery will not take charge, then it needs replacing.

While you are changing your battery, Read this handy article about the correct Lanyard Length.

Breakaway Switch Kit includes Waterproof Rubber Cover

Breakaway switch incl waterproof rubber cover is designed to help prevent water ingress into your breakaway switch.

Water and dirt enter the switching mechanism making it inoperable. As a result, the switch should be replaced.

Shorten the breakaway switch lanyard for effective breaking when your caravan is on its safety chains.

Finally, all trailers over 2000kg require a breakaway switch.
