Blue Sea Systems HD-Series: High-Current Battery Isolation with AFD

Reliable Power Management for 12V and 24V Systems

The Blue Sea 600A HD-Series Battery Switch is engineered for high-demand electrical systems found in large marine vessels, RVs, and off-grid setups. Designed to manage high-amperage battery banks, this switch allows you to toggle a single battery bank to a single load group with confidence. Its ignition-protected design makes it safe for installation in gasoline engine rooms, while the robust construction ensures longevity in harsh marine and automotive environments.

Protect Your Charging System with AFD

A key feature of this model is the Alternator Field Disconnect (AFD). In the event the battery switch is accidentally turned to the 'OFF' position while the engine is running, the AFD interrupts the alternator field current before the main circuit is broken. This prevents voltage spikes that can destroy the diodes in your alternator, saving you from costly repairs and electrical downtime compared to standard isolation switches.

Built for Heavy-Duty Applications

Capable of handling continuous loads of 600A (when wired with adequate cabling), this switch is ideal for diesel engines and systems with significant power draws. The 1/2" (approx. M12) tinned copper studs provide maximum conductivity and corrosion resistance, accepting large battery cables equipped with heavy-duty lugs. The versatile case design offers flexibility, supporting both surface mounting and rear panel installation to suit your specific layout.

  • High Current Rating: Handles 600A continuous and 1750A cranking (30 sec), ideal for heavy diesel starting loads.
  • Alternator Protection: Integrated AFD safeguards your alternator diodes during accidental switching.
  • Ignition Protected: Safe for use on gasoline-powered boats and within engine compartments (SAE J1171).
  • Flexible Connection: Accepts two 4/0 AWG (approx. 120mm²) cables per terminal to meet maximum current ratings.
  • Versatile Mounting: Fits standard panel cutouts or surface mounts with 1/4" (approx. M6) hardware.

Applications and Compatibility

This master battery switch is perfectly suited for managing main power in boats, camper trailers, and 4x4 setups running 12V or 24V systems (Rated up to 32V DC). Whether you are upgrading your marine electrical system or building a robust dual-battery setup for an RV, the HD-Series provides the safety and reliability required for professional-grade installations.

Secure your electrical system today. Equip your vessel or vehicle with the Blue Sea HD-Series Switch for safe, heavy-duty isolation.

The Best!
Color: Croissant
Out of all the stuffable, freezable dog treat toys I’ve tried over many years with several dogs, this one is #1! So easy to clean and freezing the little goodie cup that you insert in to the toy is so much easier than trying to stuff a small hole! The extra little grooves on the outside I fill with no sugar no salt peanut butter and my pup loves it! This is a heavier toy, so not sure how a small dog would do picking it up or carrying it around, but our 45 lb guy has no problem! Seems like it is very durable and just might last forever!

Bump on tongue
Color: Croissant, Color: Croissant
It’s a good idea but should be made with hard rubber and the back should not be able to come off. It gives off shards of plastic and gave my dog bumps on his tongue. I do love the idea and it keep my dog busy in the morning while I had my first cup of coffee and before everyone woke up.

My dog loves these
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
I think this is the 2nd or third I have ordered of this toy. My shepherd mix absolutely loves them. He is a power chewer and these last a few weeks. The shape is great too - he quickly learned how to hold on to it with his paws for maximum chewing efficiency.
