It is a fuse-only component — no holder or base included — sized for the NH000 form factor common in European motor control centres and distribution boards.
The aM curve means the fuse is designed to withstand motor inrush without nuisance blowing, then clear a fault quickly once the current exceeds the overload region. At 32 A rated current and 690 V AC rated operational voltage, it is sized for a motor branch circuit up to roughly 15 kW on a 400 V three-phase system, provided the prospective short-circuit current stays within the fuse's breaking capacity — which the aM class typically handles up to 50 kA or more at 690 V, though the exact value should be confirmed from the manufacturer's time-current curve for the specific coordination study.
DIN NH fuses of this size and curve are standard in motor feeder protection within industrial control panels, switchgear, and motor control centres (MCCs) across Europe and markets that follow IEC 60269. The NH000 form factor fits into the corresponding fuse holder or switch-disconnector base, and the aM characteristic coordinates with contactors and overload relays to provide Type 2 coordination per IEC 60947-4-1.
