ABB 7126.120 Junction Box - CE RoHS
Part Number: 7126.120
Quick Summary
ABB 7126.120 Junction Box is a hollow-wall enclosure designed to house a single electrical fitting in hollow-wall installations. This compact solution helps avoid exposed wiring and misalignment when retrofitting in limited wall cavities. It carries CE and RoHS declarations, along with REACH compliance, and aligns with ABB’s EU Declaration of Conformity for hollow-wall boxes HW50-G. By combining a tough plastic enclosure with a screw-based mounting and a snap-on cover plate, it delivers reliable, fast installation while maintaining regulatory compliance. For project teams and maintenance crews, the box offers predictable performance, easy accessory compatibility (revolving ring, feed-through via nozzle, and double nozzle options), and consistent quality across installs.
