The ABB ACS510-01-09A4-4 is an inverter drive in the ACS510 series, ordered under ASEA BROWN BOVERI as the "09" model with A4 terminal style and -4 enclosure. The "-4" suffix in the order code is the enclosure class for that 380 - 480 V family, and "A4" denotes the terminal layout on this frame — meaning the same drive carries different terminal hardware across the series even when the supply window is identical.
Mechanical envelope and handling
The unit weighs 8.2 Kg and ships at 9.5 Kg, with a wall-mount footprint of 12 cm x 13 cm x 59.5 cm — a tall, narrow profile that drops onto a backplate without consuming DIN width. The mass is manageable for a single installer to handle on a wall bracket without a lift assist, but the height of the chassis still wants a second pair of hands when it goes above shoulder level. Wall-mounted architecture, not panel-through, means the heatsink stays inside the cabinet and the keypad faces outward — the layout a retrofit job on an existing MCC cubicle usually needs rather than a flange-mount cutout.
