Blue metal junction box for electronic projects

This blue metal enclosure measures 270 by 140 by 210 millimetres externally and provides a protected space for power supply units, amplifiers and student builds. The inner cavity is 245 by 120 by 192 millimetres and the box weighs 1320 grams. It is supplied new as a single unit with a built-in handle for transport.

Thermals, noise and power draw in normal use

The metal construction acts as a natural heat sink, helping to dissipate warmth from installed components without any moving parts. Because there are no fans, the enclosure adds zero acoustic noise to the environment. It draws no power itself and simply houses the devices you fit inside.

Build quality and daily handling

The robust metal shell delivers electromagnetic field protection and is rated for excellent waterproof and dampproof performance. A surface-mount design lets you fix the box directly to walls or panels, while the integrated handle makes it easy to reposition during prototyping or field work. The blue finish identifies the unit at a glance in busy workshops.

Questions about this item

How do I surface-mount this 270x140x210mm junction box and what step is often missed?

Drill mounting holes through the rear wall using the outer 245x192mm footprint, then seal every screw head with waterproof washers — skipping the washers lets moisture in.

What maintenance will this blue metal enclosure need over time?

Inspect the lid gasket annually for compression set, clean any corrosion from the hinge pin, and re-torque the cover screws to keep the waterproof rating intact.

What is the first limit I hit when running a high-wattage power supply inside this box continuously?

The 210mm internal height and solid metal walls limit passive heat dissipation, so component temperatures rise until you add forced-air vents or an external heatsink.
