Introduction

If you’re stepping up to a 1200V system, you want gear that’s just as dependable as your lower-voltage parts. YRO’s 1200V junction box takes everything customers appreciated about our 550V model—easy-open latches, extra lock, modern design, built-in protection—and builds in the capability to handle higher voltages, safely. You still get that clean, updated look, that makes the box feel like a high-end piece of equipment, not some clunky accessory. Whether it’s installed on a commercial rooftop, or tucked into a ground-mounted skirting, the enclosure stays sealed against dust, rain, and curious critters.

Inside, the layout is intuitive. Protective elements like fuses, surge protection, and safety disconnects are all mounted on a single backing plate. That means when you open the cover, everything you need is right there—no stray parts, or confusing bundles of wire. We mark each connection clearly so you don’t have to second-guess your wiring. And if you’ve got a unique setup—maybe different string lengths, a branded interior panel, or a non-standard mounting footprint—just give us the dimensions. We’ll adjust both the box size and the placement of everything inside to make your life easier.

Despite handling higher voltage, the snap-in clips remain effortless to operate. The extra lock helps ensure only authorized folks gain access, and the IP65 rating makes this box tough enough for coastal environments, dusty deserts, or any place in between. And because YRO manages design, manufacturing, and assembly in one place, we keep tight control on quality, without sneaking in extra costs. The result is a premium-feel box at an accessible price point.

Features

  • CE-Certified: Meets rigorous European certification for high-voltage safety.
  • IP65-Rated Durability: Keeps water and debris out, even in harsh outdoor conditions.
  • Modern Visual Design: Blends into any installation environment with sleek lines and subtle color.
  • Additional Security Lock: Extra safeguard to prevent unauthorized opening.
  • User-Friendly Latches: Redesigned for smooth, tool-free operation every time.
  • Integrated Protection Components: Fuses, surge arresters, and disconnects ready to go.

Details

When you open the enclosure, you’ll see all components neatly arranged on a single mounting plate. This layout not only makes inspection and maintenance easier but also simplifies the wiring process. The edges of the waterproof housing are smoothly rounded to prevent cable damage, and the enclosure is made from high-quality plastic, that withstands prolonged exposure to heat, humidity, and dusty or sandy environments. Standard mounting holes on the back are compatible with commonly used rail systems, making installation much more, straightforward.
