BUNKER INDUST Trailer Breakaway Kit — 12V 5Ah Battery, LED Charge Display & Charger, Side-Mount Safety

The BUNKER INDUST Trailer Brake Breakaway Kit is a complete 12V safety system that automatically applies your trailer's electric brakes if it separates from the tow vehicle.

Designed for trailers already fitted with electric brakes, this all-in-one kit combines a breakaway unit, a rechargeable 12V 5Ah battery, an LED charge display and an easy-to-use switch to give riders and caravan owners a dependable emergency-stop solution. The compact side-mount housing is weather and corrosion resistant, and the included charger simplifies maintenance so the system is ready when you need it.

How does the breakaway kit protect my trailer when it detaches?

If a trailer separates from the tow vehicle, the breakaway switch triggers the unit to send power from the installed 12V battery to the trailer's electric brakes, bringing the trailer to a controlled stop. The system engages immediately when the switch is pulled, reducing runaway risk and helping prevent accidents.

• Breakaway switch activates electric brakes on separation
• 12V 5Ah battery supplies reserve power for brake application
• Instant engagement minimizes uncontrolled trailer movement

What features help me keep the kit charged and ready?

The kit includes a charger and an LED display that shows battery status so you can verify readiness at a glance. A push-to-test function indicates whether the battery is fully charged, currently charging, or requires recharge, making pre-trip checks quick and reliable.

• LED indicators for charged, charging, or needs recharge
• Push-to-test button for easy battery checks before departure
• Onboard charger maintains battery health between uses

How easy is installation and where does the unit mount?

The breakaway unit is designed for side-mount installation and comes as a complete kit containing the breakaway unit, battery and switch, so no additional primary components are required. Weather-resistant construction and straightforward wiring make installation manageable for experienced DIYers or professional fitters.

• Complete kit: breakaway unit, 12V 5Ah battery, and switch included
• Side-mount housing reduces intrusion into cargo areas
• Weather- and corrosion-resistant materials for outdoor use

Will this work with my trailer's electric brake system?

This unit is intended for trailers that already have an electric brake setup; it integrates with that existing system to power the brakes during an emergency. Confirm compatibility with your trailer's brake controller and wiring before purchase, and consult a technician if you have a non-standard electrical system.

• Designed to interface with existing electric brake systems
• Requires proper wiring to the trailer brake circuit for operation
• Professional installation recommended for complex electrical setups
