{"product_id":"qbp426225","title":"Blue Sea Systems ATO\/ATC-Style Low Profile Circuit Breaker, For ST-Blade Fuse Blocks, 32V DC, Thermal Trip, Manual Reset, 2pk","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Blue Sea Systems ATO\/ATC-Style Low Profile is a manually resettable circuit breaker made to replace standard ATO and ATC blade-style fuses in compatible DC fuse blocks. It gives boat owners a cleaner way to handle branch circuit protection because a tripped circuit can be reset with the push button rather than replacing a fuse after each overload event.\u003c\/p\u003e\u003cp\u003eThis low-profile breaker is rated for up to 32V DC and uses a thermal trip with manual reset. It has an interrupt capacity of 2000A at 28V DC and operates from -30° C to 77° C, which makes it suitable for common marine DC panels, small electronics circuits, pumps, lighting runs, and accessory loads when the correct amperage is matched to the wire and circuit.\u003c\/p\u003e\u003cp\u003eThe breaker fits ATO and ATC blade fuse locations and works with Blue Sea Systems ST-Blade fuse blocks, including water-resistant ST-Blade fuse blocks when the cover is secured. It is a practical option for boats where fast serviceability matters, such as fishing consoles, helm panels, cabin accessory circuits, and small DC distribution panels.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eDrop-in replacement for ATO and ATC blade-style fuses in compatible fuse blocks.\u003c\/li\u003e\n\u003cli\u003eManual push-button reset helps restore a protected circuit without carrying spare fuses for that amperage.\u003c\/li\u003e\n\u003cli\u003eThermal trip, manual reset breaker type for DC branch circuit protection.\u003c\/li\u003e\n\u003cli\u003eMaximum voltage rating of 32V DC for common 12V and 24V boat electrical systems.\u003c\/li\u003e\n\u003cli\u003eInterrupt capacity of 2000A at 28V DC for protection against high fault current within its rating.\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -30° C to 77° C for engine-adjacent spaces, helm panels, and cabins exposed to seasonal temperature swings.\u003c\/li\u003e\n\u003cli\u003eCompatible with Water-Resistant ST-Blade Fuse Blocks when the cover is secured, and compatible with other ST-Blade Fuse Blocks without a cover.\u003c\/li\u003e\n\u003cli\u003eAvailable in 5A, 7.5A, 10A, 15A, 20A, 25A, and 30A ratings to match different protected circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product range varies by amperage rating, with options from 5A through 30A. The selected amperage should match the protected circuit, wire size, and equipment requirements rather than the accessory alone.\u003c\/p\u003e\u003cp\u003eThe low-profile ATO\/ATC blade format, 32V DC maximum voltage rating, thermal trip with manual reset, 2000A interrupt capacity at 28V DC, and ST-Blade fuse block compatibility remain consistent across the range.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eInstall this breaker in the same type of fuse position used for an ATO or ATC blade fuse. The push-button reset should remain accessible after installation, especially in helm and distribution panels where a circuit may need to be checked quickly underway or at the dock.\u003c\/p\u003e\u003cp\u003eBefore replacing a fuse with a resettable breaker, confirm the circuit amperage, conductor size, and connected load. A resettable breaker should not be used to increase the rating of an existing circuit, and any repeated trip should be treated as a wiring or load issue that needs inspection.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis breaker is a good match for boat owners and technicians who already use ATO\/ATC-style DC fuse positions and want reset capability without changing the fuse block layout. It fits Blue Sea Systems ST-Blade fuse blocks and is especially useful in locations where small DC circuits are grouped together, such as electronics panels, switch panels, and accessory distribution blocks.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\u003cli\u003eTwo ATO\/ATC-style low profile circuit breakers in the selected amperage.\u003c\/li\u003e\u003c\/ul\u003e","brand":"Blue Sea Systems","offers":[{"title":"10A","offer_id":52023070785717,"sku":"QBP426225-V0","price":15.99,"currency_code":"USD","in_stock":true},{"title":"15A","offer_id":52023070818485,"sku":"QBP426225-V2","price":15.99,"currency_code":"USD","in_stock":true},{"title":"20A","offer_id":52023070851253,"sku":"QBP426225-V3","price":15.99,"currency_code":"USD","in_stock":true},{"title":"25A","offer_id":52023070884021,"sku":"QBP426225-V4","price":15.99,"currency_code":"USD","in_stock":true},{"title":"30A","offer_id":52023070916789,"sku":"QBP426225-V5","price":15.99,"currency_code":"USD","in_stock":true},{"title":"5A","offer_id":52023070949557,"sku":"QBP426225-V9","price":15.99,"currency_code":"USD","in_stock":true},{"title":"7.5A","offer_id":52023070982325,"sku":"QBP426225-V6","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1333385_qbp426225.jpg?v=1780191652","url":"https:\/\/www.qualityboatparts.com\/products\/qbp426225","provider":"Quality Boat Parts","version":"1.0","type":"link"}
