IP67 DC12-48V Waterproof Car Circuit Breaker 100A Dc Circuit Breaker

DC12-48V Waterproof 100A Mini Circuit Breaker Marine Audio Reset Switch

Description:

Universal 12-48V DC Marine and Automotive Protection:
Designed for boats, RVs, and cars, this 100A circuit breaker operates across 12-48V DC systems. Safeguards high-power marine stereos, battery banks, and electronics from overloads in wet environments while supporting audio amplifiers and dual-battery setups with universal voltage compatibility.

Manual Reset Safety with Waterproof Housing:
IP67-rated waterproof casing prevents corrosion in bilges or engine bays. Features tactile manual reset lever for reliable short-circuit response (3kA breaking capacity) and C-curve tripping - ensuring instant cutoff during emergencies without fuse replacements.

100A High-Current Performance:
Handles continuous 100A loads with precision copper contacts to prevent voltage drops. Thermally stable up to 85°C for demanding applications: subwoofers, winches, inverters, or solar controllers where surge currents exceed standard fuses.

Marine-Grade Mini Construction:
Compact thermoplastic housing resists saltwater, UV exposure, and vibrations. Exceeds ISO 8846 standards with -40°C cold-crank tolerance - ideal for tight stereo compartments or battery trays in boats/RVs where space is critical.

Inline Fuse Replacement and Simplified Installation:
Directly replaces traditional blade fuses with tool-free M8 terminals (accepts 4-8 AWG wires). Visible trip indicators enable quick diagnostics during maintenance while sealed gaskets prevent moisture ingress in marine environments.
