Sierra BS11010 AFD battery switch

SIERRA BS11010 AFD Battery Switch | Ultimate Marine Electrical Protection

Ensure the safety, reliability, and longevity of your vessel´s electrical system with the SIERRA BS11010 AFD Battery Switch. Engineered for the demanding marine environment, this premium switch provides robust control over your boat´s power, protecting your critical components from damage and preventing unwanted battery drain. It is the definitive choice for boat owners who refuse to compromise on quality and safety.

The standout feature of the BS11010 is its integrated Alternator Field Disconnect (AFD) circuit. This essential technology is designed to safeguard your engine´s alternator, one of the most vital and expensive parts of your charging system. Should the switch be accidentally turned to the "OFF" position while the engine is running, the AFD circuit breaks the alternator´s field connection before the main power circuit is disconnected. This prevents catastrophic voltage spikes that can destroy the alternator´s sensitive diodes, saving you from costly repairs and time off the water.

Key Benefits:

* Complete Alternator Protection: The built-in AFD functionality provides peace of mind by automatically protecting your alternator from accidental switching, a common and expensive mistake.
* Enhanced Onboard Safety: As an ignition-protected switch, it is certified safe for installation in gasoline engine compartments. It allows for a rapid and complete shutdown of the electrical system in an emergency, minimizing fire hazards.
* Superior Durability and Longevity: Constructed to withstand the harshest marine conditions, the switch features a rugged, UV-stabilized housing that resists degradation from sunlight and a fully sealed IP66 waterproof design that protects internal components from powerful water jets and corrosion.
* Optimal Electrical Performance: Tinned-copper terminal studs offer maximum electrical conductivity and superior corrosion resistance compared to standard brass or copper, ensuring a reliable, low-resistance connection for years to come.
* Effective Power Management: Isolate your battery or battery bank from the electrical system during storage to eliminate parasitic drain from electronics, clocks, and other small loads. This extends the life of your battery and ensures you have power when you need it.
