It provides overcurrent protection for the windlass motor circuit, tripping on sustained overloads while tolerating the high inrush current that occurs during normal windlass startup and operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e70A rating\u003c\/strong\u003e — matched to the typical current draw of compatible Lewmar windlass systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlow-blow thermal magnetic design\u003c\/strong\u003e — tolerates startup inrush current without nuisance tripping, while protecting against sustained overloads and short circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWindlass-specific application\u003c\/strong\u003e — engineered for the high-current, intermittent-duty cycle of electric anchor windlass motor circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLewmar OEM part\u003c\/strong\u003e — direct replacement for compatible Lewmar windlass installations specifying a 70A breaker\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplication\u003c\/h3\u003e\u003cp\u003eThis breaker is used in the main power circuit between the battery bank and the windlass contactor\/motor. It protects the wiring and motor from damage in the event of a short circuit, wiring fault, or sustained mechanical overload. The breaker is typically mounted in an accessible location near the battery or in the anchor locker.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatch to your windlass model:\u003c\/strong\u003e Confirm the Lewmar wiring diagram for your specific windlass specifies a 70A breaker before ordering. Some Lewmar models require a different amperage — using an undersized breaker causes nuisance trips; an oversized breaker may not protect the wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlow-blow is required:\u003c\/strong\u003e Standard fast-blow breakers will trip on windlass startup inrush current. This slow-blow thermal magnetic design is specifically rated for motor circuits with high startup loads — do not substitute a standard automotive or panel breaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire sizing matters:\u003c\/strong\u003e The breaker protects the wire, not just the motor. Confirm your cable run length and gauge are correct for 70A continuous service before installation.
