{"product_id":"qbp218987","title":"Blue Sea Systems ST CLB Circuit Breaker Block Jumper, 5-Pack","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Blue Sea Systems 5049 is a jumper for ST CLB circuit breaker blocks that bridges two adjacent circuits on the block. It is used when a layout calls for tied circuits instead of keeping every breaker position isolated, and it comes in a 5-pack for new installs, panel changes, or keeping spares on board.\u003c\/p\u003e\u003cp\u003eIt fits Blue Sea Systems ST CLB breaker block layouts, including the 6-circuit and 12-circuit versions with or without a negative bus. In those systems, the compatible breaker blocks are used on 32V DC circuits and allow up to 40A per jumped circuit group, so this jumper matters when you are planning how adjacent protected circuits will be combined on the block.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eLinks two adjacent positions on a Blue Sea Systems ST CLB circuit breaker block\u003c\/li\u003e\n\u003cli\u003eFits ST CLB breaker block models 5050, 5051, 5052, and 5054\u003c\/li\u003e\n\u003cli\u003eUsed for jumped circuit group layouts where separate positions need to be tied together on the block\u003c\/li\u003e\n\u003cli\u003eKeeps the connection at the block instead of adding a short external jumper wire\u003c\/li\u003e\n\u003cli\u003eSold as a 5-pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis part is not a breaker and not a fuse. It is a connection accessory for ST CLB breaker blocks, so the main fit question is the block family on your boat. If the panel uses another breaker block or another terminal layout, this jumper is not the right piece.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe jumper mounts across two terminal screws on the breaker block. That keeps the connection easy to inspect later and helps the distribution area stay cleaner than a hand-made wire link, especially in tight helm, cabin, or accessory panel spaces where service access matters.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis is a practical add-on for refits or new builds that use ST CLB blocks for lighting, pumps, electronics, or other DC branch circuits and need adjacent positions tied together. It also suits installers who want a consistent block layout instead of mixing in custom jumpers during the job.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\u003cli\u003eFive ST CLB circuit breaker block jumpers\u003c\/li\u003e\u003c\/ul\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":52023141007541,"sku":"QBP218987","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1329957_qbp218987.jpg?v=1780191779","url":"https:\/\/www.qualityboatparts.com\/products\/qbp218987","provider":"Quality Boat Parts","version":"1.0","type":"link"}
