syizyen 5 Way Circuit Breaker Box, IP65 Distribution Protection Box with Din Rail Abs Plastic Breaker Box Cover Miniature Electrical Breaker Box Enclosure for Indoor Outdoor Wall

Why I picked up this five‑way breaker box

I needed a compact, weather‑resistant home for a handful of miniature breakers on a small solar sub‑array and an EVSE branch. The usual metal NEMA enclosures were overkill on size and price, and I wanted a clear door so I could check breaker positions at a glance. That’s where this IP65, five‑module ABS enclosure came in. I’ve since used it outdoors on a shaded wall and on a workshop column, and it’s performed well within the constraints of its size.

For clarity, I’ll refer to it as the 5‑way breaker box.

What’s in the box

• ABS enclosure with a hinged, clear front door and perimeter gasket
• Short length of 35 mm DIN rail prepped for five 18 mm modules
• Four mounting screws
• Two small silicone sleeves for cable pass‑throughs

There are no cable glands, no knockouts, and no neutral/earth bars included. You’ll need to plan for those.

Build quality and weather protection

The body is ash‑colored ABS with a smoked clear door. The plastic isn’t tank‑like, but once mounted to a solid surface the enclosure feels stable. The hinge is basic and the latch is positive; after a few dozen open/close cycles it hasn’t loosened. The included DIN rail is standard 35 mm steel and accepts typical MCBs, RCBOs/GFCI MCBs, and slim DIN‑mount accessories without issue.

The IP65 claim lives or dies on your cable entries. The door gasket seals evenly and the cover screws cinch down nicely, so the box itself is ready. I drilled my own entries and fitted threaded cable glands; after a few minutes of heavy hose spray from different angles, the interior stayed dry. In real weather (wind‑driven rain for a couple weeks), no ingress. I’d still avoid direct sprinkler blast or locations with constant sun bake; ABS can chalk over time. If you must mount in full sun, consider a shade or UV‑resistant paint.

Installation experience

Mounting is straightforward: four screws through the back into anchors, and you’re done. The bosses are molded well and didn’t crack when torqued reasonably.

Cable entries are DIY. There are no knockouts. I marked centers, drilled pilot holes, and opened them up with a step bit to match my glands (M16 for 12–14 AWG sheathed cable and M20 for heavier runs). Deburr inside and out so the gland gaskets seat properly. The two included silicone sleeves can be used for small, light‑duty pass‑throughs, but they aren’t a substitute for proper glands or cord grips if you want to preserve the IP rating and provide strain relief.

The rail clips to molded posts. I pre‑mounted breakers on the rail, then snapped the assembly in; that was easier than trying to latch breakers in the box. The clear door provides enough clearance for standard single‑pole MCBs and a two‑module GFCI breaker, but taller relays/contactors can get close to the door—check depth if you plan non‑breaker components.

Capacity and wire management

This is the most important consideration. The rail holds five 18 mm positions, but the wiring volume is tight. With five single‑pole MCBs and solid 10 AWG conductors, you’ll be fighting bend radii. In my solar setup, two single‑pole breakers and a two‑module GFCI MCB plus a set of compact DIN terminals felt like the practical maximum while maintaining tidy routing and stress‑free bends.

A few tips that helped:

• Favor fine‑stranded conductors with ferrules over solid conductors when code allows; they bend cleaner in tight spaces.
• Use compact DIN terminal blocks and jumpers for neutrals and grounds instead of trying to shoehorn full‑size bar kits. The enclosure doesn’t include neutral/earth bars, and there aren’t dedicated standoffs for them.
• Route incoming on the bottom and outgoing on the top (or vice versa) to keep conductors from crossing in front of the breakers.
• Pre‑cut short, measured pigtails and label everything before installation; there’s not much room to pull slack later.

If you know you’ll land multiple 10 AWG solids or add accessories like surge protection, consider stepping up to the next larger size. The 5‑way works brilliantly for compact builds, but it rewards restraint.

Everyday use

The clear door is more useful than it looks. I can walk by and confirm breaker positions without opening the enclosure, which is handy in dusty environments. The latch keeps the door shut against the gasket without needing over‑tightening, and the seal hasn’t taken a set in mild temperatures.

Indoors, it’s a clean, compact distribution point for a workbench or tool bay. Outdoors, with proper glands and thoughtful routing, it’s a capable little weatherproof box for small solar arrays, pump circuits, or EVSE feeder protection. The ABS body doesn’t ring or vibrate, and there’s no rattling from the rail once everything’s snug.

What I like

• Compact footprint that still accepts five standard modules
• Clear, gasketed door that makes status checks easy
• True 35 mm DIN rail included and aligned
• IP65 sealing achievable with proper glands and careful drilling
• Good value given the hardware included

What could be better

• No knockouts: every entry must be drilled, which adds time and requires the right tools
• No neutral/earth bars or provisions to mount them cleanly; plan on DIN terminals
• Limited wiring volume; large solid conductors are a squeeze
• ABS shell feels thin compared to metal NEMA boxes; fine when mounted, less confidence if abused
• No listing info on the enclosure body; for permitted work, verify approvals or choose a listed alternative

Sizing guidance and alternatives

Think in terms of modules and volume. If your design includes:

• Up to three single‑pole MCBs and light gauge conductors: the 5‑way is a great fit.
• One two‑module GFCI/RCBO plus two singles, with a couple of DIN terminals: still fine.
• Heavy 10 AWG solid conductors, surge protection, contactors, or more than three circuits: go one size larger so you can route neatly and maintain bend radii without stress.

If you need factory knockouts, integrated neutral/ground bars, or a UL/NEMA rating printed right on the box for inspection, a steel NEMA 3R/4 enclosure with a DIN backplate may be a better (if pricier) choice.

Safety and code notes

As with any enclosure, the IP rating assumes correct cable glands and proper torque on covers. Don’t rely on the included silicone sleeves for strain relief in outdoor runs. If you’re working under permit, verify the enclosure meets your local listing requirements and that your breakers and terminals are rated for the environment and conductor types you’re using. Ferrules are your friend with stranded conductors, and torque drivers prevent cracked terminals in tight quarters.

The bottom line

The 5‑way breaker box hits a sweet spot for small, neat DIN‑rail builds where you need weather resistance, visibility, and a tight footprint. Its strengths are the clear gasketed door, standard rail, and value; its weaknesses are wiring volume and the lack of built‑in cable management (knockouts, bars). Installers comfortable drilling clean entries and using compact DIN terminals will get a tidy, reliable result. If you’re planning heavier wiring or lots of devices, choose the next size up.

Recommendation: I recommend this box for compact indoor/outdoor projects that need up to five DIN modules and benefit from a clear door, provided you’re ready to drill your own entries and supply glands and terminals. For larger conductors, crowded layouts, or inspection‑driven jobs that demand listed metal enclosures with integrated bars and knockouts, step up to a bigger, listed alternative.
