The DF2FGA63 is a TeSys GS DIN NH000 aM blade fuse, rated 63 A at 690 V AC, supplied as a set of three. It's a protection device for motor branch circuits and feeder lines, sized for the NH000 fuse holder footprint.
The 63 A rated current and aM (motor-protection) curve mean this fuse handles motor starting inrush without nuisance blowing, while still clearing short-circuit faults. The NH000 form factor fits standard DIN NH000 fuse bases and disconnects.
This part is listed as obsolete.
