Blue Sea Systems A-Series Toggle Single Pole Circuit Breakers

Like all other Blue Sea Systems products this cover worked as it should.

It did what it said it would. I needed to stop a breaker in my panel from being turned on.

does the job. my panel is low and often critical circuits get turned off accidentally - this 'cover' prevents accidental shut off and is still easy to operate by flipping the plastic cover to access the switch.Only down side is it cannot be used to protect the 12v Master circuit breaker.

Fit perfectly over my breaker switches. My panel is located where I had accidentally brushed against them turning on some components without realizing it...ran batteries dead. This prevents this from happening. Looks great, very functional and great quality.

Fits perfectly on Blue Sea breakers, of course. Includes screws, too. Price changes significantly and frequently as the item goes back and forth between Prime and non-Prime, so keep watch to save a few bucks on each one you order.

Very helpful in keeping switches from being accidently turned on or off. Can cover a switch on or off. I elected to use these for now instead of building a Plexiglas door to cover the entire panel

These did just what I needed - provided and extra layer of protection for critical circuits that I don't want inadvertently turned off.

Terminals on back are held by thin plastic and break easily. I had a 10ga wire on the terminal and while inserting the breaker into the panel box it broke the back out of the breaker. May be ok for low amperages, but not over 20a where the cables are heavier or stiff.

These are perfect on a boat/RV switch panel to avoid turning critical loads off or on by accident (eg. refrigerator, battery charger, AC panel on/off, etc). I put three on my panels for these switches as my guests would sometimes flip these switches off when leaving the boat and I’d return to the boat the following week with spoiled food, and drained batteries. When installed, flipping a breaker is a two step process, so must be deliberate. Open the cover, flip the breaker, then close the cover. My only complaint is that it is difficult to see the breaker position through the very small hole although all my breakers have an on/off LED next to them which shows status. Nonetheless, it would be nice if these were clear rather than black plastic like the breaker switch and panel.
