Rittal KX 1578000 E-Box, Carbon Steel
The Rittal KX 1578000 is a 300 × 600 × 155 mm carbon steel E-Box with a 275 × 585 mm mounting plate. Its tall format provides extended vertical mounting space while keeping the enclosure width to 300 mm, allowing equipment to be arranged in a longer vertical sequence without moving to a wider housing.
With 585 mm of mounting height, KX 1578000 provides substantially more vertical layout space than the shorter 300 mm-wide KX sizes. The 155 mm enclosure depth also provides room for components that project further from the mounting plate, while the 275 mm mounting width keeps the overall format relatively narrow.

KX 1578000 keeps the 300 mm width and 155 mm depth of KX 1577000 but adds 200 mm of enclosure and mounting-plate height. Choose it when the 385 mm-high mounting plate of KX 1577000 cannot hold the required equipment rows and wiring zones. KX 1579000 adds another 200 mm of height, but its 785 mm-high mounting plate is only useful when the completed layout genuinely needs that longer vertical run.

Set the enclosure orientation and cable-entry direction before locating openings. On the 300 × 600 mm housing, top and bottom entries must preserve the end wiring zones, while side openings must be checked against the narrow 275 mm mounting width and every vertical equipment row. Door cut-outs must also clear both lock positions and the hinge line shown in the current Rittal dimensional drawing. Show reference edges, center coordinates, dimensions and tolerances on the machining drawing.
For review, provide: KX 1578000, 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 300 × 600 × 155 mm dimensions do not define usable internal clearance.
