Overview
The DF2HN1251 is a Schneider TeSys GS DIN NH1 blade fuse, order code DF2HN1251, rated 250 A at 500 V AC with a gG (general-purpose) fuse curve. Supplied as a set of 3 in a PCE package, it is part of the DF range within the TeSys GS line for motor and circuit protection.
This blade fuse uses a gG curve, meaning it provides full-range overcurrent protection for cables and general loads — not just motor starting surges. The 250 A rating at 500 V AC suits distribution panels and switch-disconnectors where the NH1 size fits standard fuse bases. The DIN form factor ensures mechanical interchangeability with other NH1 holders.
Applications
Used in motor switch-disconnectors and fuse-protected circuits within industrial control panels, TeSys GS fuses like the DF2HN1251 protect branch circuits feeding motors, transformers, and resistive loads. Common in OEM machinery, conveyor systems, and pump stations where NH-size fuses are specified for high-fault-current coordination.
