It comes as a set of three identical fuses, without striker, for three-phase motor branch circuits.
The aM curve means this fuse is designed for motor-starting inrush — it carries the starting surge without nuisance opening, then clears a sustained overload or short-circuit. The 40 A rating at 690 V AC covers standard 400 V three-phase motor circuits up to roughly 18.5 kW (depending on motor full-load current and coordination study). The NH000 form factor fits standard DIN fuse holders and disconnectors in the TeSys GS range.
Deployment context
The DIN NH000 blade format mounts in panel-mount fuse bases or switch-disconnectors on standard DIN rail, common in motor control centers and distribution boards for industrial machinery.
