Knife type (NH) fuse-links gG class for general use, with top indicator. These high breaking capacity fuse-links are intended for
500V
protection of power lines and equipment, against overloads and short-circuits with rated voltages up to 500V AC (+10%). The
rated breaking capacity is 120 kA. The range comprises fuse-links from size NH000 up to NH4, with rated currents from 2A up
to 1250A. Compact versions in low rated currents of every size. Manufactured with ceramic body with high withstand to internal pressure and thermal shock, that allows a high breaking capacity. Knife contacts are made of silver plated copper or brass.
They are manufactured according to IEC/EN60269 and VDE0636 Standards and comply with RoHS directive.

Knife type (NH) fuse-links aM class for motor protection, with top indicator. These high breaking capacity fuse-links are inten500V
690V
ded for short circuit protection in motors, transformer and other load with high inrush currents, with rated voltages up to 500V
AC (+10%) and 690V AC (+5%). The rated breaking capacity is 80 kA at 690V or 120 kA at 500V. Excellent protection of switchgear (contactor, thermal switch) due to the good current limiting capability and low I2t values. These fuse links must be associated to an overload device protection (thermal switch). The range comprises fuse-links from size NH000 up to NH4, with rated
currents from 6A up to 1250A. Compact versions in low rated currents of every size. Manufactured with ceramic body with high
withstand to internal pressure and thermal shock, that allows a high breaking capacity. Melting elements are silver plated in
order to avoid the aging and thus keep unalterable the electric characteristics. Knife contacts are made of silver plated copper
or brass. They are manufactured according to IEC/EN60269 and VDE0636 Standards and comply with RoHS directive.

Knife type (NH) fuse-links, aM class for motor protection, with striker. Intended to be used with microswitch fuse bases These
500V
690V
high breaking capacity fuse-links are intended for short circuit protection in motors, transformer and other load with high inrush
currents, with rated voltages of 500V AC (+10%) or 690V AC (+5%). The rated breaking capacity is 80 kA at 690V or 120 kA at
500V. Excellent protection of switchgear (contactor, thermal switch) due to the good current limiting capability and low I2t values.
These fuse links must be associated to an overload device protection (thermal switch). The range comprises fuse-links from size
NH0 up to NH4, with rated currents from 32A up to 1250A. Manufactured with ceramic body with high withstand to internal
pressure and thermal shock, that allows a high breaking capacity. Melting elements are silver plated in order to avoid the aging
and thus keep unalterable the electric characteristics. Knife contacts are made of silver plated copper or brass. They are manufactured according to IEC/EN60269 and VDE0636 Standards and comply with RoHS directive.

DC APPLICATIONS
FUSE LINKS are generally suitable for both AC and DC applications. The DC performance of fuse-links is different and AC ratings cannot be used
for DC applications. There is no simple rule that safely converts an AC voltage rating of a fuse-link to DC voltage rating. For this reason it is
necessary to take into account a lot of aspects in order to determine the DC applications.
In the DF ELECTRIC gG NH fuse links it is necessary to take into account the following considerations:
• The power dissipations are the same in AC (RMS value) and the DC values.
• The time current characteristics are the same for DC applications under steady-state conditions.
• The DC rated voltage and maximum breaking capacity are lower than the AC values (see the table).

These values are referred to a time constant L/R = 15 ms.
For higher values of time constant, the maximum utilization voltage must be reduced.
For circuits with very inductive behaviour, we recommend to connect two fuse links in series.
