Upgrade your boat's power management with the Blue Sea Systems e-Series Dual Circuit Battery Switch, model 5510E-BSS. This switch offers a 350 Amps continuous rating, perfect for inboard gasoline or diesel engines. Its tin-plated copper studs provide excellent conductivity and corrosion resistance, and it can accept up to 4/0 AWG battery cables. With a 7/8' (22mm) stud length, it easily fits multiple cable terminals. The one-piece terminal stud design ensures it never loosens over time. It fits most Perko and Guest low amperage battery switch hole patterns and offers surface, rear, or front panel mounting options. The tactile indicator lets you feel the knob position. It's waterproof (rated IP66) and ignition protected, making it safe for gasoline-powered boats. Specifications include a red color, 2 switch positions, no battery combine or alternator field disconnect, a maximum voltage of 32V DC, and more.
Using the Blue Sea E-Series Dual Circuit On-Off Battery Switch is straightforward. First, make sure your boat's power is off. Then, connect the battery cables to the appropriate terminals, following the cable size recommendations (up to 4/0 AWG). When mounting, choose between surface, rear, or front panel mounting according to your boat's setup. To operate, simply turn the knob to the desired position. Remember, this switch is ignition protected, so it's safe for gasoline-powered boats. When it comes to maintenance, regularly check the terminal studs for tightness. Since the studs are tin-plated copper, they're resistant to corrosion, but a visual inspection every now and then can help ensure optimal performance. Avoid using abrasive materials on the switch case. If the switch gets wet, it's waterproof (rated IP66), but you can dry it with a soft cloth. Always follow the torque specifications when tightening the terminal studs (140 in-lb or 15.82 Nm). This will keep your battery switch working well for a long time.
