QILIPSU 12 Way UL94-V0 Circuit Breaker Box IP65 Waterproof PC/ABS Alloy Plastic MCB Panel Solar Power Distribution Enclosure with DIN Rail, Bus Bars for Indoor and Outdoor Use

Why I picked this compact breaker enclosure

I needed a small, tidy, weather-resistant way to mount DIN-rail breakers for a compact distribution build—something that wouldn’t rust, would keep fingers out of live parts, and could live indoors or out without fuss. The QILIPSU 12-way breaker box checked most of those boxes on paper: IP65 rating, UL94 V-0 PC/ABS alloy housing, a preinstalled DIN rail, full slot covers, and included copper bars for neutral/ground. After a full install and a couple of weeks of use (including a rain test), here’s how it performed.

Build quality and materials

The enclosure feels more premium than a lot of generic plastic boxes in this size class. The V-0 PC/ABS alloy has a dense, rigid feel without the brittleness you sometimes get in hard plastics. The housing walls are thick, the hinge is positive, and the latch closes cleanly. The door and the inner breaker trim both use compressible gaskets, and the fit is precise enough that you don’t have to fight the cover to get screws started.

The inner trim plate is well designed: it frames the breaker toggles and blocks access to the terminals, so once your wiring is complete and the trim is on, you get a finger-safe front. The kit I received included full slot covers that snap in snugly to blank off any unused ways—an easy win for both safety and a cleaner look.

The copper bus bars (neutral/ground) are nicely machined and plated, with consistent threads and square, positive clamping. They’re rated 63 A, which is sensible for a 12-way enclosure intended for typical branch-circuit work or DC distribution. Keep in mind they’re not sized for very large conductors; more on that below.

Dimensions are 273 x 230 x 110 mm (10.7 x 9.1 x 4.3 inches). It’s compact for a 12-way box, and that compactness is part of the appeal—and occasionally part of the challenge.

Layout, capacity, and wire management

Inside, the standard 35 mm DIN rail arrives preinstalled and aligned. I loaded it with 1P DIN breakers and a couple of ancillary modules (a surge protective device and a small relay), and capacity was exactly what you’d expect: 12 standard 18 mm modules. The internal geometry gives you just enough wire space to route neatly if you plan ahead. For typical 15–20 A branch circuits or DC strings, it’s a straightforward, clean layout.

As with any compact enclosure, larger conductors eat space quickly. I tested fit with #6 AWG THHN to a 62 A DC breaker—the bend radii and landing angles are doable but tight. If you’re working with fine-stranded solar cable, ferrules help a lot, both at the breakers and on the included bus bars. Once I committed to tidy routing and dressed the runs, the door closed without pressure on the conductors.

The bus bars work well for distributing neutrals and grounds (or DC returns), but they aren’t intended for 4 AWG or larger feeders. If your design needs to consolidate many small circuits into heavy-gauge feeders, plan on external distribution blocks or a second enclosure to handle the big transitions.

Installation experience

Mounting is simple. The rear has molded bosses with reserved hole positions; I used stainless fasteners into wall anchors and had the box solidly mounted in minutes. There are no traditional “knockouts,” which I actually prefer in plastic enclosures. I marked my entry points, drilled pilot holes, and opened them to size with a step bit for IP-rated cable glands. The PC/ABS machines cleanly with sharp bits, leaving no cracking or stress whitening. If you want to preserve the IP65 rating, use appropriately rated glands and don’t forget to seal any unused mounting penetrations.

Once mounted, populating the rail is painless. The trim cover aligns over the breaker faces, and the full-width gasket compresses evenly when the four corner screws are snugged down. The outer door also has its own gasket and closes with a confident snap. With both gaskets in play, it’s well sealed.

Weather protection in practice

For outdoor suitability, IP65 is the headline, but the execution matters. I ran a hose test (angled spray, not a pressure washer) and saw no water ingress on the inner trim or the bus bars—exactly what I wanted. The four-screw design compresses the trim gasket well at the corners; you’ll get the best performance by tightening at opposites and not over-torquing. As with any outdoor electrical box, orient your glands downward, use drip loops, and avoid mounting in direct, pooling water. If you’re placing it fully exposed, a small overhang or shield is still smart long-term insurance.

Day-to-day usability and safety

The combination of the inner trim and snap-in slot covers makes the front genuinely finger-safe. Breaker handles are accessible, labels remain visible, and the inside remains tidy and protected from incidental contact and dust. The door hinge and latch feel solid; there’s no wobble or misalignment. The plastic composition and finish clean up easily—no powder-coated steel to chip or rust.

One thoughtful detail: the trim plate sits close enough to the breaker faces that you don’t see the conductor entries, which helps discourage curious hands from “peeking under the hood.”

Limitations and things to plan for

• Conductor size: The included bus bars are great for small to medium conductors and lots of terminations, but they aren’t meant for 4 AWG and up. If you need to land heavy feeders, add a separate set of listed distribution blocks with the right lug sizes, or upsize to a larger enclosure.
• Space is finite: If you pack the rail with tall devices (e.g., surge modules or double-height components), wire bend radii get tight. Pre-build your rail assembly on the bench and dry-fit the trim to ensure clearance.
• No knockouts: I see this as a plus for sealing and layout freedom, but it does mean you need a step bit and proper glands in your kit.
• Compliance context: This is a general-purpose distribution enclosure with an IP65 rating and V-0 flammability material. For North American mains panelboard applications that require UL-listed panelboards/load centers, verify acceptance with your AHJ. It’s perfect for DIN-rail breaker projects, controls, DC, and supplementary distribution; just match the enclosure to the code requirements of your use case.

Where it shines

• Small solar/DC distribution where you need a neat, weather-resistant box
• Outdoor or damp locations that would punish steel boxes
• Tidy sub-circuits for pumps, irrigation, gates, sheds, and similar loads
• Network/power hybrid builds where you want a DIN rail plus protected wiring space

In all of these, the combination of a sturdy, flame-resistant shell, genuine IP65 sealing, and a clean DIN layout makes the job faster and the result more professional.

What I’d improve

• Offer optional higher-capacity bus bars and/or a matching add-on bus bar kit with larger lug options.
• Add two center screws to the inner trim for an even more uniform gasket compression across very wide spans.
• Include adhesive wire labels or a small legend strip for the front—minor, but handy.

None of these are deal breakers, but they’d broaden the range of use cases and make the box even more turnkey.

The bottom line

The QILIPSU 12-way breaker box is a well-executed, compact DIN-rail enclosure that delivers on the essentials: robust plastic with a proper V-0 rating, real weather sealing, finger-safe operation with full slot covers, and a preinstalled rail and bus bars that simplify setup. It’s not meant to anchor oversized feeders or act as a heavy-duty main panel, but for small to medium distribution—AC or DC—it’s a tidy, durable solution that looks good and stands up to the elements.

Recommendation: I recommend this enclosure for anyone building a compact, IP-rated DIN-rail breaker panel where conductors are in the small-to-medium range and code requirements align with a general-purpose distribution box. It saves time, keeps installs clean and safe, and avoids the corrosion headaches of metal boxes outdoors. If your design hinges on large-gauge feeders or inspector-mandated UL panelboards, choose a larger, purpose-built load center and pair this only for supplementary circuits. For everything else in its lane, this box is easy to like and easy to live with.
