Blue Sea Systems E-Series Dual Circuit Battery Switch Model 5510E-BSS for Marine and RV Applications

Blue Sea E-Series Battery Switch On-Off Dual Circuit

The Blue Sea Systems E-Series Dual Circuit Battery Switch (Model 5510E-BSS) offers reliable and efficient battery management for marine and RV systems. Designed to handle continuous currents up to 350 amps, this switch is ideal for inboard gasoline or diesel engines, providing a robust solution to control power distribution safely. Its construction features tin-plated copper studs, ensuring maximum conductivity and resistance to corrosion, which enhances longevity and maintains optimal electrical performance over time. The switch accepts up to 4/0 AWG battery cables and is compatible with 3/8 inch (M10) ring terminals, allowing flexible installation options to suit various wiring configurations. The 7/8 inch (22mm) stud length accommodates multiple cable terminals, simplifying complex wiring setups and reducing installation time. A key feature is the one-piece terminal stud design, which prevents loosening over time and maintains a secure connection under vibration and varying environmental conditions. The switch's case design supports surface mounting, making it adaptable to different installation environments. Its compatibility with most Perko and Guest low amperage battery switch hole patterns ensures ease of replacement or upgrade in existing systems. This switch is built with durability and safety in mind, providing a dependable way to switch between batteries or isolate power sources when necessary. It also complies with Prop 65 standards, warning of potential cancer and reproductive harm, which users should consider during installation and maintenance. The Blue Sea Systems E-Series Battery Switch is an essential component for reliable power management in demanding marine, RV, and industrial applications, combining high performance with straightforward installation and corrosion resistance.
