Your cart is empty.The Suntree DC Miniature Circuit Breaker is designed to protect DC electrical installations against overloads and short circuits with both the thermal and magnetic tripping mechanism equipped. Once a fault is detected, the circuit breaker automatically switches off the electrical circuit to prevent damage to wires and avoid the risk of fire. The circuit breaker can also be manually opened under the full rated load without any damage when electrical maintenance needs to be performed. Engineered for reversible connection, the circuit breaker is allowed to be wired in either direction and functions under bidirectional current. The built-in indicator window helps identify the contact position of the circuit breaker at a glance. The buckle design enables easy installation on the standard DIN rail.

Must have one of these for a DIY RV solar setup.

Great lil box for the price minus the fact the lock is damaged from being tossed around before amazon put it in the shipping box. (Shipping box had no damage) so the lock got damaged from where ever it was packaged til when it shipped here. Other than that can’t complain. Would buy this again.

Heavy and solid electrical breaker box. I bought it to house industrial automation controllers on DIN rails in a pinch.

I love this circuit breaker, its heavy and built very well..the lugs to screw the wires are big and sturdy also it was shipped and delivered very fast.i was using a different breaker which would trip way before it get to 160amps but this one qorks very well. Would definitely reccomend..

This is not a well-designed or thought-out load center for anything but some specific pre-determined scenario the brilliant minds at Renogy decided on. In my setup, I was only able to accommodate a single MPPT controller before maxing out the negative bus bar. Adding a second charge controller isn't even possible without some creative "expansion" of the bus bars.The main busbars are limited in terms of the number of terminals, especially the battery Negative/Positive which each have only 2 bolts for lugs and two much smaller hole terminals which can't accommodate any serious gauge wire (maybe AWG 8 at best). I ended up splitting AWG 4 into 2 hole terminals by spilling the wire into 2 "strands" to make it work, albeit in a crude way.If you are planning on using it as a combiner for PV inputs, it's limited to only 4 strings (I have a separate combiner box, so only had 1 set of black/red cables from the PV array).Ironically, the biggest bus bar is for the ground wires, which makes no sense as in all likelihood, the other bus bars will be maxed out long before the grounding busbar.Also, pre-stamped "concentric" holes are all located on the bottom of the unit only and none on the top or sides, so I had to drill out all those for my setup (see photos)And if I were to nitpick, the pre-drilled mounting holes are too close to the corners of the box, which makes it very challenging to use any kind of drill/driver to get at them (not enough clearance). I ended up drilling out other holes, so I can easily access them with a driver.All in all, another example of a crappy Chinese design. Next time, I'll probably just splurge on a Midnight Solar load center.

This breaker is the perfect solution for my solar batteries. I use it for a 48 volt system. the safety release works great. This unit is very easy to install with rugged connections. I like that it has dividers between the posts for safety and that it breaks both posts. It is a large unit but it is the best option for a great price. I haven't tested the breaker with excess amperage but I see no reason it won't function as required, I have came very close to the rated amperage and it doesn't get hot.

The breakers were used, you can't trust a used breaker !!!! from someone else !!!The breakers were just in a brown paper bag, no bubble wrap or anything.No GOODLook at the pictures you can tell they were used breakers !!!! for the same price !!!

Seems very well made and certainly beastly enough. Lug connections are plenty big for 2/0 lugs. I always wonder about devices that say rated for 200 amps (or such) and then have small bolt downs for lugs - this is not one of those. Hard to test of course - I don't want to make a 160 amp short for a long enough duration to trip it, so I have to leave faith to the fact that it works or not. The test button works, and manually throwing the breaker is no joke, an effort with a big clunk.
