Lwuey 2 Way Breaker Box, Din Rail Box MCB Distribution Protection Box IP65 Waterproof Circuit Breaker Electronic Junction Box Transparent Cover Power Electrical Enclosure Outdoor Wall Mounted Charging

Why I reached for a compact DIN enclosure

I put the Lwuey 2‑way box to work on a small project that needed just a pair of modules: a main miniature circuit breaker and a low-voltage control switch with an indicator. Space was tight, the install was partially exposed to weather, and I wanted to see status without cracking open an enclosure. On paper, this little two-module IP65 box checked those boxes: ABS construction, a steel DIN rail inside, and a smoke‑gray transparent cover you can snap open with one hand.

Build quality and materials

For something this compact, the build feels reassuring. The ABS walls are thicker than the “budget” enclosures I’ve used, with minimal flex when you press on the sides. The molded hinge and latch on the cover engage cleanly and don’t feel sloppy. Inside, the DIN rail is steel and square to the back, and the standoffs that hold it don’t wobble. The whole housing is insulated, which matters if you’re mounting it in tight quarters near metal framing or conduit.

The transparent gray lid strikes a good balance: it’s dark enough to hide scuffs but clear enough to read breaker levers and indicator LEDs at a glance. After several weeks of sun exposure, I didn’t see any yellowing or clouding.

Weather protection that holds up

The Lwuey 2‑way box is rated IP65, and the gasket design backs that up. There’s a full-perimeter seal in the lid, plus an inner lip that sheds water before it reaches the gasket. With properly installed cable glands, I hosed the enclosure from all directions and didn’t find moisture inside. It’s not for submersion or direct high-pressure wash, but for rain, wind-driven spray, and dusty environments, it’s appropriately tight.

A quick note: the IP rating assumes you’ll use glands or sealed fittings for all cable entries. Bare knockouts or loose bushings will compromise the seal, so plan your entries before you commit to hole locations.

Layout and usability

Two modules mean exactly that: space for either a single 2‑pole breaker or two 1‑pole devices. The rail spacing and depth accommodate standard 18 mm DIN modules without pinching the wiring. I had enough room to route 12 AWG conductors with ferrules and still close the lid without pressure.

The visibility through the lid is genuinely useful. Being able to see a tripped indicator (or the status LED on a small DC switch-mode device) without opening the box is a real convenience for quick checks and remote equipment corners.

The snap latch is firm. With bare hands, it opens easily; with gloves, you’ll want a thumb on the hinge side to steady the lid as you pop it. The hinge is molded plastic, not a pin, but feels sturdy and doesn’t bind.

Installation: straightforward but plan your entries

Mounting is straightforward. The box has internal bosses so you can fasten it to a wall or panel with four screws. You’ll need to open the lid to access them, which keeps the fasteners outside the weather seal and maintains the IP rating. I appreciated that the rail sits high enough to route conductors under it if you’re neat with your bends, which helps in such a small footprint.

Where you’ll want a bit of patience is cable entry. The enclosure provides pre-marked locations for knockouts on the ends, roughly aligning with the rail and device terminals. That alignment makes for a neat, short wiring path. However, the scoring on a couple of the knockout positions was conservative. On one box, I could push out the end knockout with a step bit and light pressure. On another, I needed a Dremel to finish the cut cleanly. It’s not a deal-breaker, but don’t expect “tap-it-with-a-screwdriver-and-go” knockouts. Bring a step bit and deburring tool to keep the edges clean for your glands.

For sealing hardware, common M16/M20 cable glands fit the available real estate; I used M20 on the ends for mains and M16 on the side for a low-voltage pigtail. There are no glands in the box, so order what you need ahead of time.

Performance in typical use cases

I’ve used this enclosure in three scenarios:

• Outdoor switch protection for a small pump, where the box sits under an eave and needs to survive blowing rain. No ingress issues, and the transparent lid made it easy to verify the breaker position from the ground.
• A bench setup for reactivating a lithium battery module with a DIN-mounted DC switch and voltmeter. The small footprint kept the setup tidy, and the insulated body gave me peace of mind around other metal fixtures.
• An indoor retrofit where the ability to see an indicator lamp without opening the enclosure saved time during commissioning.

In all cases, the combination of sturdy ABS, a confident latch, and clear visibility added up to a workmanlike experience. Heat buildup wasn’t an issue; two modules don’t generate much heat, and the enclosure doesn’t trap excessive warmth in mild sun.

What I’d improve

• Friendlier knockouts: Pre-marked is fine, but the scoring could be deeper and more consistent so you can remove them without power tools. This is the most noticeable friction point.
• Include grommets or a basic gland kit: At least a pair of M20 glands would help first-time installers preserve the IP rating without a separate order.
• Lid grip: The latch works, but a slightly larger lip would make gloved operation easier.

None of these are fundamental flaws, but they are the small touches that separate a good enclosure from a great one.

Comparisons and value

Two-module DIN boxes are a crowded space, ranging from ultra-cheap housings that feel brittle to heavy polycarbonate enclosures that cost as much as a small distribution panel. The Lwuey 2‑way box lands in the sensible middle: noticeably sturdier than bargain-bin options, with a real gasket and a rail that doesn’t wobble, yet still compact and reasonably priced. The transparent lid alone makes it more useful than opaque equivalents if you value quick visual checks.

If you need room for terminals, a surge protector, or segregated low-voltage wiring, go up to a 4- or 6‑module enclosure. This box is purpose-built for two modules; it doesn’t pretend to be more.

Safety notes

As with any enclosure work: de-energize before installing, use glands sized to your cable diameter, and torque device terminals properly. The box is insulated, but don’t rely on the plastic body for protective separation where codes require additional measures. For outdoor installs, orient entries downward and add drip loops.

Bottom line

The Lwuey 2‑way box is a solid little enclosure for protecting a pair of DIN modules indoors or out, with a genuinely useful clear lid and IP65 sealing that holds up when you use proper glands. It feels robust in the hand, the DIN rail is aligned and sturdy, and the layout keeps wiring short and direct. The only real annoyance is the inconsistency of the knockouts; expect to cut them cleanly rather than “pop” them. If you can live with that, the overall experience is reliably good.

Recommendation: I recommend this box for compact installations where you need two DIN modules and appreciate a clear, weather-sealed lid—think small outdoor switches, pump controls, or neat bench setups. It’s not the fanciest enclosure, but it’s sturdy, practical, and keeps the elements out. Plan your cable entry hardware and bring a step bit, and it will do exactly what it should without fuss.
