The ABB 3ABD00018831 is an ACS510-01-038A-4+C135 variable frequency drive rated for 18.5 kW normal-use output power and 38 A normal-use output current, on a 380-500 V three-phase supply. It carries an IP21 degree of protection and a NEMA Type 1 enclosure, making it suitable for indoor installations where drips and falling dirt are a concern. The drive is wall-mounted and carries the IE2 efficiency class. Frequency range is 47.5 to 63 Hz, covering 50/60 Hz mains.
The C135 option code indicates a variant for flange mounting, but the mounting set is not included. The wall-mounted enclosure requires clearance for airflow around the IP21-rated chassis. Verify gland-plate access for incoming power and motor cables before panel layout.
