High-Performance 600V Double Pole DC Circuit Breaker for Solar PV Systems

Safeguard your photovoltaic and battery storage infrastructure with this robust double pole DC breaker, engineered specifically for the demands of direct current environments. Designed for caravan, marine, industrial and off-grid PV systems. These circuit breakers provide essential protection against overcurrents and short circuits, this miniature circuit breaker (MCB) ensures that your off-grid, marine, or caravan electrical systems operate with maximum safety and reliability. Featuring a 40A capacity, it is perfectly sized to protect specific DC load requirements while maintaining stable power flow.

Advanced Arc Fault and Overcurrent Protection

Direct current circuits present unique challenges compared to standard alternating current, particularly when it comes to extinguishing electrical arcs during a fault. Utilizing sophisticated thermo-magnetic trip technology, this DC circuit breaker is explicitly designed to detect and safely interrupt harmful DC arcs up to 600V. By swiftly disconnecting the circuit during an overload or short circuit, it significantly mitigates the risk of cable damage, electrical fires, and catastrophic equipment failure. This makes it an indispensable safety device for 12V, 24V, and 48V battery systems, as well as high-voltage solar arrays.

Non-Polarised Design for Safer, Simpler Installation

A major advantage of this specific solar MCB is its non-polarised architecture. Traditional polarised breakers require strict adherence to current flow direction, which can lead to dangerous failures if wired incorrectly or if reverse currents occur during complex battery charging cycles. The non-polarised nature of this breaker eliminates the risk of directional wiring errors, allowing safe bidirectional current flow. This simplifies the installation process for both professional auto-electricians and off-grid enthusiasts while drastically reducing potential safety hazards.

Key Features

  • 40A rated capacity to suit your specific array or battery load specifications
  • Non-polarised internal design safely handles bidirectional current without risking internal damage
  • 6kA short-circuit breaking capacity (Ics/Icu) ensures reliable interruption of severe electrical faults
  • 6kV impulse withstand voltage (Uimp) provides exceptional resilience against system surges
  • Standard DIN rail compatibility allows for rapid, secure mounting in standard electrical enclosures
  • Clear visual status indicators confirm isolation state at a glance for safe maintenance

Built Tough for Demanding Environments

Constructed with high-quality, flame-retardant thermoplastic, this 2 pole DC circuit breaker is designed to meet strict IEC/EN 60947-2 standards. It features a Pollution Degree 3 rating, meaning it is built to withstand the ingress of dust and moisture commonly experienced in demanding Australian applications, including remote off-grid sheds, camper trailers, and marine engine bays. The secure tunnel terminals ensure excellent cable retention, minimizing resistance and preventing the development of dangerous hot spots over the lifespan of your installation.

Ensure the longevity and safety of your renewable energy architecture by integrating this highly reliable Exotronic 40A 2-Pole DC Circuit Breaker (MCB) into your distribution board today.

Great Energy Outlet for an Active Dog!
Size: 4 INCH, Pattern Name: IQ TREAT BALL 4"
I have a 1 year old Australian Shepherd/Border Collie/Cattle Dog mix named Josie. When you look up "hyper-active dog" in the dictionary, you'll find her picture. She could run for days if she wanted to. I am always looking for things to help keep her from getting bored, and this treat ball is great! She was only about 3 or 4 months old when I got this and introduced it to her. With a little help from me, she figured it out in no time. Now she's a pro, and knows exactly how to paw at the ball to make it spin and fling food out. I have the 5-inch ball. Josie's not a big dog (40lbs) and she can get her mouth around the ball to pick it up. She only does this when it rolls onto the linoleum floor in the kitchen. I think it gets too loud for her (and me too!). I always put it away when the food is gone so she doesn't use it as a chew toy. She has never gotten bored of pushing it around and decided to chew on it. She can hear the food rattling around inside and continues to play with it until it is empty. This isn't the type of toy that you would give to your dog, and then leave them unsupervised. The ball is made out of hard plastic, and does make a loud banging when it runs into walls, chairs, etc., but it has never left any marks on my walls or furniture. I actually prefer she use it on the carpet because it's quieter and she always gets all of the food pieces (it works just as well on carpet as it does on a hard floor, fyi). If I lived on the bottom floor or in my own house, I wouldn't have a problem with her using it on hard floors, however she always brings it back to the carpet on her own when it rolls off. I like that the hole on the middle divider is adjustable, and you can also just take the middle part out of the ball so you can fit more food inside, the dog can see the food so they're more motivated to get it, or to make it easier for a younger/older dog to get food out. My dog loves this ball. She gets excited when I take it out and start filling it with food. With the divider it has enough room for half of her portion. She always goes for the ball first, empties it, then to her dish. When she's done eating she always lays down and takes a nice long nap. I know that she enjoys it, and it definitely gives her 15-20 minutes of good, mentally-stimulating indoor exercise. It also taps into their prey-drive, and I think that helps make your dog feel like a dog. Overall this is another great buy from Amazon. I did see it at the pet store (after I had gotten mine) for double the price! ***If you have a dog that is food-motivated and needs something to do, buy this. It's worth it.***

Great toy while it lasts
Size: 3 INCH, Pattern Name: IQ TREAT BALL 3"
We purchased one of these for our 10 pound Malshipoo as she gets bored easily and this thing definitely keeps her busy for awhile while she tries to get the treats out. She rolls and kicks it hard enough that I'm sometimes fearful it will break but after having owned it for 14 months it's actually held together quite nicely to my surprise. I think it came apart once and that's probably because I didn't have it screwed on correctly. The only reason I didn't rate it higher was two things: First, I don't like that the top section is in two parts and you have to fit them together just right for it to screw on. Why not make it one solid piece on the top? The second reason I didn't rate it higher is the white plate with the hole you twist to make the hole bigger or smaller is now a lot looser so when our dog bangs this against a wall or anything hard the hole shifts and makes it bigger thus the game doesn't last as long. So I'm purchasing a new one and hoping this doesn't happen again. I guess it's just wear and tear but I would have like it to last longer than 14 months. Maybe I guess my expectations aren't realistic. Hopefully the next one lasts longer.

This is a good toy to keep some dogs busy
Size: 4 INCH, Pattern Name: IQ TREAT BALL 4"
I purchased this for my pitbull that is very food driven. One thing I first noticed about this ball is the type plastic it's made of. It's similar to the plastic they use for some cheap hamster balls. I would be cautious If you live in a two story home that doesn't have carpeted stairs because this my break after falling down the stairs or a few drops from a few feet. If you have a small dog, be cautious if they bite onto the ball because they can get their teeth stuck in the small holes. I would also advise people with large dogs with strong jaws from this toy because if they crush this plastic, the edges will be sharp enough to cut their mouths. The first thing you would have to do is adjust the center white disc to the size of the treats. If you make the hole too big, too many treats will fall out too fast and it will shorten the time you dog will play with this. You can put small training training treats or dog food in the bottom half of the ball. I use my dogs food for my dog. Be mindful of the amount of the treat's calories and the quantity you put in the ball. Just make sure you account the extra calories for the amount of exercise your dog receives otherwise you may have a chubby doggy. After filling the bottom half and placing the white disc on top of it, all you have to do is screw on the top and its ready for your dog to work for their tasty snacks. I wouldn't have given this to my dog when she was younger because was the type of dog that would of destroyed the toy when she was aggravated with it just to get to the treats. Now she's learned to figure out toys before she brings it to me to help her out. I usually fill it up with some low calorie food and when she gets down to the last few bits, she gives up on the toy and leaves it where it is or brings it back to me to open it up for the last few pieces. I was surprised after several uses, the lid never accidentally came unscrewed while my dog was playing with it. Overall this is a good toy to keep my dog occupied for 20-30 minutes. Shes a pretty smart dog and shes learned how to get the treats out fairly quick. Your mileage may vary depending on the size and shape of your treats you put in.

Kept our dog busy!
Color: Navy Blue, Color: Navy Blue
We have a 4 month old corgi and he is obsessed with this toy. The puzzle pieces move really easily so they are able to get into it but also create enough of a puzzle for them to move around.

Challenging for my experienced puzzle players, sturdy all in one.
Color: Navy Blue
My girls love this treat puzzle; it is not for a first timer. My dogs have several of these and they cannot get the hand of spinning the light blue circle to move the small red covers. It is a challenge and that is what they need to give me some me time.
