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.

A good start to the story
Format: Kindle
This was definitely entertaining, and the cliffhanger left me curious to see what happens next. Addi is definitely a bad ass and she has to prove herself Day in and Day out because of what she is. I love that. She never cowards and always rises to a challenge. She doesn’t let anyone push her and she always has a comeback for any prejudice thing said to her. I’m looking for more from the guys cause so far I’m honestly unimpressed. They definitely have some growth and helping within these next few books I’ll see that growth and like them a little more.

OUTSTANDING
Format: Kindle
This was very, very good. The world is vast and characters are complex. There is a good plot with a whole lot going on. This is well written. Good twists and turns and some heart breaking moments. You will love these characters, they have heart and loyalty. I am hoping that there will be several more books. We've yet to see anything from the Sea Court but only a mention of them here and there. The Wood Court was given a quick couple of scenes, and only as far as some warriors, we've yet to enter their court and the Shadow Court, I'm not sure if they will be a force for good or bad, but they definitely will play a much bigger role moving forward. This is primarily the Ice and Air Courts. Told in multiple views, which I loved, it gives you a chance to see things from different eyes. There's alot of political maneuvering and deception. I loved it and will pick up the next book as it becomes available. If you like The Fae and the courts, you should love this. I think the author has mucn in store for us.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.
