Rittal KX 1553000 E-Box,carbon steel

If the layout needs more mounting area rather than additional depth, compare other KX E-Box sizes before confirming the article number.

Do You Need More Depth or More Mounting Area?

The 120 mm depth of KX 1553000 is useful when a small assembly includes components that project farther from the mounting plate or needs additional room behind the wiring. The mounting plate itself is only 125 × 135 mm, so this model is better suited to a small number of deeper components than to a large number of devices arranged side by side.

If the equipment fits within this mounting area but needs more clearance toward the door, KX 1553000 is worth considering. If the layout is already crowded across the mounting plate, increasing enclosure width or height is the more relevant change.

Standard Supply

Check Component Fit Before Ordering

Start with the 125 × 135 mm mounting plate rather than the external enclosure dimensions. Arrange the terminals, relays or other devices on this area first and leave enough room for wiring between them.

Next, check how far the installed components, terminals and conductors project toward the door. This is where the 120 mm enclosure depth becomes relevant. Cable-entry positions also need to be considered at this stage, since an opening or gland can interfere with equipment inside a small 150 × 150 mm housing.

For other accessory categories or another enclosure size, return to the KX E-Box series page. Confirm every accessory against the enclosure material, width and connection arrangement rather than assuming all KX accessories fit every model.

Machining the 150 × 150 mm Housing

Set the enclosure orientation before locating cable entries or other openings. The extra housing depth does not create more space on the 150 × 150 mm faces, so each opening must be checked against the mounting plate, installed equipment and current Rittal dimensional drawing. Show reference edges, center coordinates, dimensions and tolerances on the machining drawing.

For review, provide: KX 1553000, quantity, an approved drawing or CAD file, opening sizes and positions, tolerances and cable-entry direction. Confirm the final drawing before machining because the external 150 × 150 × 120 mm dimensions do not define usable internal clearance.
