Product overview
It is designed for DIN-style fuse holders in panel protection circuits.
The 80 A line-rated current and 690 V AC operational voltage define the maximum continuous load and system voltage this fuse can interrupt under fault. The aM curve means it tolerates motor inrush without nuisance blowing — it holds through the start-up transient of induction motors and similar inductive loads, then clears on sustained overcurrent. The NH0 blade size matches standard NH0 fuse bases and switch-disconnectors common in European-style distribution panels.
Deployment context
This fuse set mounts into DIN-rail NH0 fuse bases inside industrial control panels — typically upstream of motor starters, variable frequency drives, or transformer feeders where the aM curve provides selective coordination with downstream overload relays.
