Blue Sea E-Series Battery Switch 1-Off-2-Both With AFD

The Blue Sea Systems 9002E-BSS e-Series Selector Battery Switch with AFD provides reliable power management for boats with multiple battery banks. Designed to handle continuous currents up to 350 amps, this switch is ideal for inboard gasoline or diesel engines, ensuring safe and efficient operation. Its robust construction features tin-plated copper studs, which maximize conductivity and resist corrosion, extending the lifespan of your electrical system. The switch accepts up to 4/0 AWG battery cables and includes 3/8 inch (M10) ring terminal studs with a 7/8 inch (22mm) length to accommodate multiple cable configurations. The one-piece terminal stud design guarantees that the connection remains tight over time, reducing maintenance concerns.

The switch's versatile case design allows for surface or rear panel mounting, making installation flexible in various boat layouts. A tactile indicator on the knob conveys its position by feel, enabling quick and confident operation even in challenging conditions. With an IP66 waterproof rating, the switch is resistant to water jets, ensuring reliable performance in wet environments. It is ignition protected and safe for installation aboard gasoline-powered boats, meeting strict safety standards. The make-before-break contact design allows switching between battery banks without interrupting power, maintaining system stability during operation. Additionally, the switch includes an Alternator Field Disconnect (AFD), providing further control over your charging system.

This 4-position selector switch can isolate individual battery banks or connect them to all loads, offering flexibility in managing your boat’s power sources. It features a maximum voltage rating of 32V DC, with terminal torque specifications to ensure secure connections. The switch supports a continuous rating of 350 amps and a short-term intermittent rating up to 600 amps, with a cranking capacity of 1200 amps for 30 seconds. Compatible with most Perko and Guest low amperage battery switch hole patterns, the Blue Sea Systems 9002E-BSS is a durable, versatile, and essential component for marine electrical systems seeking reliable and safe power switching solutions.
