Lewmar 90AMP Circuit Breaker

Protecting your boat's anchoring system starts with reliable components like the Lewmar 90 amp circuit breaker. Designed specifically for demanding marine environments, this breaker snaps into action to safeguard windlass motors from overloads, short circuits, and other electrical faults that could leave you stranded at anchor. Boat owners who tackle rough seas or frequent anchoring know the frustration of a failed windlass— this unit steps in as your first line of defense, ensuring smooth operation every time you drop or retrieve the hook.

Engineered for Marine Windlass Demands

Built to withstand the vibrations, moisture, and corrosion typical of onboard use, this 90 amp breaker features a robust thermal-magnetic trip mechanism. It resets manually after tripping, allowing quick recovery without tools, which is a game-changer during unexpected power surges from battery fluctuations or motor stalls. Unlike generic automotive breakers, it's rated for continuous duty in wet locations, meeting stringent marine standards for safety and longevity.

• High interrupt capacity: Handles fault currents up to 3,000 amps for superior protection.
• Compact design: Mounts easily on panels or bulkheads with standard 1/4-inch terminals.
• Water-resistant housing: IP66 rating keeps salt spray and splashes at bay.
• Visual trip indicator: Clear status at a glance, no guessing games.

Why It Outshines Standard Breakers

Imagine heaving-to in choppy conditions, only for your windlass to draw excessive amps from a fouled chain— this breaker trips instantly, preventing motor burnout and potential fire risks. It's not just about breaking the circuit; it's about precision. Calibrated for windlass loads between 60-90 amps, it avoids nuisance trips during legitimate high-draw moments like initial motor startup, yet activates reliably under true overloads. Boaters upgrading from older setups report fewer replacements and more peace of mind, especially on larger vessels with heavy ground tackle.

Seamless Integration with Your Setup

Pairing perfectly with popular Lewmar windlasses handling rodes up to 1/2-inch diameter, it slots into existing control boxes or custom panels. For DIY installers, it's straightforward: disconnect power, swap terminals, and secure with the provided studs. Pro tip— always fuse upstream for layered protection, and use tinned marine wire to match its durability. If you're retrofitting, check your windlass draw (typically stamped on the motor) to confirm 90 amps fits your power curve.

Common Compatibility Matches

• Windlasses from mid-range to heavy-duty models.
• 12V or 24V DC systems on sailboats, powerboats, and yachts.
• Control panels with DIN-style mounts.

Long-Term Reliability Tips

To maximize lifespan, inspect terminals annually for corrosion— a quick vinegar soak works wonders. Avoid undersized batteries that spike amperage, and consider a windlass controller for soft-start features that reduce stress. Saltwater veterans swear by dielectric grease on connections to fend off oxidation. With proper care, this breaker outlasts the average by years, saving you downtime and repair headaches.
