MAKERELE 4 Way Outdoor Circuit Breaker Box Power IP66 PC/ABS Waterproof Distribution Protection Box for MCB Miniature Circuit Breaker with Transparent Cover and DIN Rail 4.13 x 3.94 x 7.68 inch

Why I reached for this box

I needed a compact, weather-resistant enclosure to cleanly house a few DIN-rail miniature circuit breakers for a small outdoor project: one feed, a couple of branch circuits, and a tidy way to keep terminations dry. The Makerele 4‑way outdoor breaker box fit that brief on paper—IP66 rating, translucent cover, and a DIN rail in a small footprint (about 4.13 x 3.94 x 7.68 inches). After installing and living with it for a few weeks, here’s how it holds up.

Build and materials

The enclosure is molded from a PC/ABS alloy, and it feels notably more rigid than basic ABS boxes I’ve used. Wall thickness is decent for the size, and the body doesn’t flex much under conduit stress (within reason). The cover is translucent and hinged, with a simple latch. There’s a perimeter gasket where the front mates to the rear body, and a separate seal around the clear door. Fit and finish are clean—no sharp flash and the latch closes positively.

A detail to understand up front: the “knockouts” are really molded guides—circles on the top and bottom that show where to create entries. They’re not true knockouts you can whack out with a screwdriver. Plan on using a step bit or hole saw and adding proper cable glands or conduit fittings. That’s the right way to maintain the IP66 claim anyway, so I didn’t mind.

Inside, the box ships with an aluminum DIN rail sized for four standard 18 mm modules. There are no bus bars, terminal blocks, or glands included. That’s not unusual for a compact distribution enclosure, but it’s important to plan your bill of materials accordingly.

Capacity and layout

This is a four-position box, and that’s exactly what you get. Four single-pole MCBs (18 mm each), or two double-width devices, or some combination plus blanking plates. The rail is positioned well, but space around the devices is tight. You can work with 12 AWG conductors comfortably; 10 AWG is doable if you pay attention to bend radii and keep your terminations compact.

The interior depth is adequate for standard DIN MCBs and most compact accessories (like a tiny surge device), but don’t expect to fit bulky add-ons or distribution blocks without crowding. I added a small neutral/ground bar on the side using adhesive-backed standoffs and stainless screws; it fit, but just barely. If you need room for more than four circuits or chunky add-ons, stepping up to a larger enclosure will save you time and frustration.

Installation

Mounting is straightforward. The back has predefined hole positions for wall mounting; I used stainless screws and nylon spacers to keep the back slightly off the surface for drainage and airflow. Laying out entries was easy with the molded guides. I drilled with a step bit and fitted IP68 cable glands for the branch circuits and a threaded hub for the main feed.

A few practical tips from the install:

• Pre-drill and deburr carefully—thin plastic can grab a bit if you rush.
• Use proper glands or threaded hubs to preserve the seal. Don’t rely on improvised grommets.
• Externally secure your conduit so the box isn’t bearing weight. The PC/ABS is strong, but it’s still plastic.
• Plan your wire routing before mounting devices to the DIN rail. Space is tight; dress conductors cleanly to avoid fighting the cover later.

The cover comes off with four screws beneath the translucent door. They bite well and compress the gasket evenly. I prefer captive screws, but at this price point, standard machine screws are common.

Weather resistance in practice

IP66 essentially means dust-tight and protected against powerful water jets. I mounted the box vertically and gave it an aggressive garden hose test from multiple angles. The door and body gaskets did their job—no visible ingress. A second round after I added glands and conduit produced the same result.

That said, any small enclosure is only as weatherproof as its field penetrations. If you drill sloppy holes, skip glands, or leave threads unsealed, you’ll compromise the rating. I added a dab of non-hardening sealant at the gland locknut and around the threaded hub, and I always create drip loops on cables. Mounted in full exposure, I’d still prefer a small hood above the top edge. Not mandatory, but it’s cheap insurance in driving rain.

Day-to-day use

The translucent cover is genuinely useful. I can check breaker positions at a glance without opening the door. The latch is easy to operate with gloves and hasn’t popped open in wind. There’s no locking provision built in; if you need to restrict access, you’ll need to add a small hasp or position it within a locked area.

Routine maintenance is painless. The DIN rail placement leaves enough knuckle room to reset devices, and the gasket stays put when you remove the front cover for deeper work. I recommend keeping a couple of blank modules on hand to fill unused positions and keep the interior tidy.

Safety, standards, and compatibility

A few caveats to consider:

• Breakers: This enclosure is for DIN-rail miniature circuit breakers (MCBs). Make sure your devices match standard 18 mm module sizing.
• Standards: The box itself doesn’t carry US-centric listings like UL/NEMA on the model I used. That may or may not matter depending on your jurisdiction and application. For permanent residential or commercial installs governed by strict code, verify acceptability with your AHJ before you commit.
• Bonding and terminations: No bus bars or terminals are included. Plan to add appropriately rated neutral/ground bars if your application requires them, and ensure proper bonding practices within your system design.

For off-grid, low-voltage, or non-permitted setups, this enclosure is an easy fit. For grid-tied or inspected work, compliance planning should come first.

What I liked

• Compact footprint with a proper DIN rail; accepts four standard modules cleanly
• Solid PC/ABS body with a snug gasketed seal
• Translucent, gasketed door for quick visual checks
• Clear molded entry guides simplify drilling
• Straightforward wall mounting and service access

What could be better

• No included bus bars, cable glands, or instructions—expect to source your own accessories
• “Knockouts” are drill guides, not punch-outs; fine for me, but expect extra steps
• Interior space is limited for distribution blocks or large-gauge conductors
• No built-in lock provision
• Lack of recognizable third-party certifications may limit where it can be used

Best-fit use cases

• Small outdoor circuits, garden or shed sub-circuits, pumps, or lighting where you need just a few breakers
• Off-grid and portable systems (solar, RV, small cabins) that use DIN-rail MCBs
• Low-voltage distribution where weather protection and organization matter more than maximum capacity

If you’re building a larger system, or you need code-listed gear for an inspected installation, a bigger, certified enclosure with integrated bars and real knockouts will save time.

The bottom line

The Makerele 4‑way outdoor breaker box is a tidy, durable little enclosure that does what it claims, provided you install it thoughtfully. The PC/ABS shell feels sturdy, the seals are competent, and the DIN rail implementation is spot-on for four modules. You’ll need to bring your own glands, bars, and attention to detail, and the tight interior won’t forgive messy wiring. It’s not a one-size-fits-all panel, but for compact DIN-rail distribution outdoors, it earns its keep.

Recommendation: I recommend this box for small, weather-exposed projects where you need up to four DIN-rail MCBs and you’re comfortable doing a clean, sealed install. It’s especially good for off-grid or low-voltage setups and protected outdoor spots. If you require listed enclosures for inspected work, need more space, or prefer true knockouts and included bus bars, look at a larger, certified alternative.
