This surface-mount device combines circuit protection and switching functions in a single unit, simplifying installation and maintenance. Its robust thermoset polyester case ensures durability in harsh environments, while the waterproof design provides added protection against moisture and water ingress. The large, easy-to-operate lever can be oriented vertically or horizontally, allowing for clear trip status indication and flexible mounting options. The recessed mounting holes contribute to a clean appearance, making it suitable for applications where aesthetics matter.\u003cbr\u003eBuilt to meet SAE J1171 external ignition protection standards, this circuit breaker is safe for installation on gasoline-powered boats and other combustible environments. The trip-free design ensures that the breaker cannot be held in the ON position during a fault condition, preventing potential damage or safety hazards. Heavy-gauge terminal studs with large clearance and high-torque terminals accommodate heavy wire lugs, facilitating secure connections for high-current circuits. Its switchable, manual-reset class makes it easy to reset after a trip, restoring power once the fault has been addressed.\u003cbr\u003eThe Blue Sea 7138 features a thermally responsive bi-metal blade that responds quickly to overloads, with an interrupt rating of up to 5,000 amperes at 12 volts DC. It operates efficiently within a temperature range of -25°C to +82°C, ensuring reliable performance across various climates. The device is rated for a maximum of 48 volts DC, making it suitable for a wide range of electrical systems. Overall, this circuit breaker provides a dependable and safety-conscious option for protecting electrical circuits in demanding environments.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCombines switching and circuit protection into a single device\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAll components meet SAE J1171 external ignition protection requirements\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eClear, single lever operation for easy status monitoring\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTrip-free design prevents holding ON during fault conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWaterproof construction for reliable operation in wet environments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRecessed mounting holes for a clean installation appearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLarge clearance around terminal studs to accept heavy gauge wire lugs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRobust 5\/16-inch terminals provide high torque connections\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLarge lever with vertical\/horizontal orientation indicates trip status\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIgnition protected for safe installation aboard gasoline-powered boats\u003c\/li\u003e\u003c\/ul\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":44530659459114,"sku":"20558","price":81.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/20558XL.jpg?v=1783124799","url":"https:\/\/atticusgoods.com\/products\/blue-sea-systems-7138-187-series-40-amp-thermal-circuit-breaker-for-marine-and-automotive-applications","provider":"Atticus Goods","version":"1.0","type":"link"}
