This 80 Amp manual circuit breaker delivers serious, resettable circuit protection for the high-current systems at the heart of your caravan, camper trailer, or 4WD electrical setup. Fully waterproof and ignition protected, it's engineered to handle the harshest conditions Australian touring throws at it — from tropical downpours to dusty outback tracks. No blown fuses to replace, no tools required — just trip, reset, and keep moving. This is the heavy-duty protection your electrical system deserves.

Serious Protection. Zero Fuss. Built for the Australian Outdoors.

When you're running a high-current 12V system in a caravan or 4WD — dual batteries, large inverters, DC-DC chargers, winches, or heavy accessory loads — the circuit breaker protecting your main feed isn't something you want to compromise on. The 80A Manual Circuit Breaker is purpose-built for exactly these demanding applications, combining heavy-duty current protection with the practicality of a resettable breaker and the ruggedness needed for life on Australian roads and tracks.

80 amps of serious circuit protection. At 80 amps, this breaker is rated for the high-current feeds that power the most demanding equipment in modern caravan and 4WD electrical systems. Main battery feeds, inverter supply cables, high-output alternator circuits, and heavy accessory loads — this breaker handles them all while standing ready to interrupt the circuit instantly if something goes wrong.

Manual reset — no fuses to carry, no replacements to find. Unlike a traditional fuse that blows and needs replacing, this circuit breaker is manually resettable. When it trips — whether from an overcurrent event or a short circuit — simply identify and resolve the fault, then reset the breaker by hand and you're back up and running. No spare fuses needed, no scrambling through the toolbox at the side of a remote track. Just reset and go.

Fully waterproof — built for all weather conditions. Australian touring doesn't stop for weather — and neither should your electrical protection. The fully waterproof construction of this circuit breaker ensures reliable performance through creek crossings, coastal humidity, heavy rain, and morning condensation. Whether it's mounted under your caravan chassis, in an exposed engine bay, or on an outdoor battery enclosure, water ingress simply isn't a concern.

Ignition protected — safe for use around fuel systems. The ignition protection rating is critical for installations near fuel tanks, fuel lines, or engines where flammable vapours may be present. This circuit breaker is designed to prevent internal sparking from igniting surrounding vapours — a non-negotiable safety feature for responsible electrical installations in caravans, boats, and 4WDs operating in environments where fuel proximity is a factor.

Manual control — doubles as a main isolation switch. Beyond its protective function, the manual circuit breaker also gives you direct control over the circuit it protects. Use it as a convenient isolation switch to disconnect your battery or accessory circuit when your rig is in storage, undergoing maintenance, or parked up for an extended period. One lever, instant isolation — no need for a separate switch.

Tough construction for the long haul. Corrugated dirt roads, extreme heat, coastal salt air, and constant vibration are all part of life for electrical components on a touring rig. This circuit breaker is built with the robust housing and heavy-duty internals needed to maintain consistent, reliable performance across thousands of kilometres of Australian travel — season after season, trip after trip.

Versatile installation options. The compact, rugged design of this breaker makes it suitable for a wide range of installation locations — battery boxes, engine bays, caravan chassis mounts, electrical enclosures, and more. Its manual operation lever is easy to access and operate even in tight spaces or with gloved hands.
