The aM curve means it's designed for motor circuit protection — it handles the inrush without nuisance blowing, then clears a sustained overload or short-circuit. The NH3 blade form factor is the standard DIN size for high-current industrial fuses, common in switch-disconnector fuse bases and fuse-switch combinations. This is a set of three fuses, so one order covers a three-phase line.
