Product Details

The AFI 2303A is a heavy-duty marine battery On/Off switch engineered for high-amperage applications in boats, RVs, and other marine electrical systems. This switch features alternator field disconnect (AFD) technology, allowing selection of any position including "Off" without damage to the alternator or electrical system. Built with a tough, glass-filled polycarbonate case, this switch is designed to withstand the harsh marine environment.

Key Features:

  • Continuous rating of 450 amps with intermittent capacity of 800 amps
  • Alternator field disconnect (AFD) protection prevents electrical system damage
  • 5/8" cable lug size for secure electrical connections
  • Compatible with 6, 12, 24, or 36 volt DC systems
  • Durable glass-filled polycarbonate construction
  • Simple On/Off operation for reliable battery control

Specifications:

  • Dimensions: 5-1/2" square x 3-1/2" deep
  • Gray color finish
  • Switch Type: Heavy-duty On/Off (single pole, single throw)
  • UPC: 046904230310

This heavy-duty switch is ideal for diesel-powered vessels, workboats, and any marine application requiring high-capacity battery isolation. The AFD feature makes it safe to switch between positions without disconnecting loads, protecting sensitive alternators and electronic equipment from voltage spikes.

USER FRIENDLY GREAT PRICE FAST SHIPPING HIGHLY RECOMMENDED PEOPLE TO DEAL WITH

Good

Excellent prices. Product was very good quality. I would recommend Autoplicity to others.

Found pics of louvers on a charger, thought it was pretty cool so I looked for some, found some, this site had lowest price so I bought me some.

Is to navigate. Found most of the parts I needed and GREAT prices.

Fantastic place to buy from. They had the best price for K&N oil filters for my motorbikes which was good enough. Then I ordered on a Saturday via normal shipping...got it Tuesday morning! Definitely going to order more in the future.

Great prices!!

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

So far so good

Everything was quick and easy. With discount for shipping, best price I could find on the internet. EDIT: Only problem I had was that the two day express shipping I had was a day late. I also never received a tracking number before I called CS. That was q

Quick and easy.
