NH fuses with operating class aM are used especially for motor protection, and unlike gG types, they are capable of interrupting only currents between a given value of overcurrent and that corresponding to its interrupting power value.
This feature is essential when high inrush currents are involved. However, the use of additional protective devices (e.g., thermal overload relays) in back-up is recommended for the protection of overcurrents below Kln. Special solutions adopted on NH aM fuse strips allow high resistance against aging caused by motor heating processes.
