Product Overview

The JL Audio XMD-MCB-80 is an 80 amp resettable circuit breaker engineered specifically for marine electrical installations. Unlike traditional blade fuses that require replacement after every fault, this unit features a manual reset switch with high-visibility indicator that simply flips back after an overload event clears. IP67 waterproof certification means the breaker survives full submersion up to 1 metre deep, while SAE J1171 External Ignition Protection approval permits installation in engine compartments and fuel tank spaces where explosive vapours may be present. Stainless steel M6 threaded studs resist saltwater corrosion far better than brass or tin-plated copper terminals. Ideal for protecting high-current marine audio amplifiers, windlass motors, live well pumps, and other 12V DC equipment drawing up to 80 amps continuous.

Manual Reset Eliminates Fuse Replacement
High-visibility toggle switch resets the breaker after an overload clears—no need to carry spare fuses or diagnose whether a fuse has blown. Saves money on consumables and reduces downtime during fishing trips or offshore runs.

IP67 Full Submersion Protection
Sealed to withstand complete immersion up to 1 metre deep for 30 minutes—critical for installations in bilge areas, wet storage compartments, or deck-mounted battery boxes where splash and spray are constant concerns in Australian coastal conditions.

SAE J1171 Engine Compartment Approved
Meets stringent ignition protection standards for installation near fuel tanks, carburettors, and engine blocks where petrol vapours accumulate. This certification is mandatory for legal compliance on many registered vessels and insurance requirements.

Stainless Steel Corrosion Resistance
M6 × 1 mm threaded studs machined from marine-grade stainless steel prevent the galvanic corrosion and oxidation that plague brass terminals in saltwater environments. Maintains reliable electrical contact even after years of exposure to salt spray and humidity.

High-Current Marine Audio Applications
Purpose-built for protecting JL Audio marine amplifiers and other high-wattage 12V equipment. The 80 amp rating suits amplifiers drawing 800–1000 watts RMS, tower speaker systems, or dual-battery setups feeding multiple loads.

Compact Surface-Mount Design
Low-profile footprint fits in tight spaces near battery terminals, distribution blocks, or fuse panels. Pre-drilled mounting holes allow secure installation on bulkheads, battery boxes, or custom fabricated brackets.
