SEAFLO 300A Battery Disconnect Switch –12V/24V/48V Heavy-Duty Isolator Switch, Single Circuit ON/Off, IP66 Waterproof, Auto, Marine, Boat, RV, Car, ATV, CE & RoHS Certified (On/Off w/No-Cover|2-Pack)

The SEAFLO 300A Battery Disconnect Switch (Model: SFCBS-300-202-A) provides secure and reliable power isolation for marine, automotive, and off-grid applications. Designed for 12V, 24V, and 48V systems, this heavy-duty switch safely disconnects a battery from a load group, preventing power drain and enhancing battery longevity. Built with high-conductivity tin-plated copper studs, this switch maximizes electrical efficiency and corrosion resistance, making it ideal for harsh marine and off-road environments. The one-piece terminal stud design ensures a secure, vibration-resistant connection that never loosens over time. With IP66 waterproof protection, this switch withstands powerful water jets, ensuring long-lasting durability in extreme conditions. Unlike the SFCBS-300-202 model, this version does not include a protective cover, making it a streamlined, cost-effective option for users who require just the switch itself. Meeting ABYC, UL 1500, and SAE J1171 safety standards, this battery switch is a trusted choice for marine, RV, automotive, and industrial power systems.
