Description
PPNI Gg type links are designed for protecting industrial electric units and cable lines from overloads and short circuit. They are manufactured per rated current from 2 to 630 A. PPNI fuse links are used for single and three-phase networks having voltage limited to 660 V (50 Hz). Application area: lead-in and distribution devices; distribution panels and boards; transformer substation equipment; low-voltage boards; control boxes and boards. Correspond to the requirements EN 60269-1.
Life time:
15 years
Warranty:
5 years
Advantages
- Power losses lowered by 30% as compared to PN-2 fuses due to the updated modern construction, manufacturing technology and quality of applied materials.
- High resistivity of receptacle (insulator) base to mechanical stress owing to the use of reinforced thermosetting plastic.
- Lowered by 10-20% overall dimensions as compared to PN-2 fuses.
- Wide range of PPNI fuse links including fusible elements with rated current from 2 to 630 A. 82 units in total in 6 sizes.
- Overload protection due to the current-limiting function providing for lowering prospective current short circuit current by several times.
- Wide range of operating temperatures: from -45 to +60 °C. It allows applying PPNI in various climate zones.
- High breaking capacity: at 660 V – 50 kA, at 500 V – 120 kA.
Design Features
Contacts of the fuse are made in the form of blade (sharpened) which allows to be installed in the holders with less effort.
The base of the holder (insulator) is made of reinforced thermosetting plastic resistant to corrosion, mechanical shock, temperature changes and dynamic shocks that occur during short circuits up to 120 kA.
The contacts of the fuse and the holder are made of electrotechnical copper with a silver coating, which prevents their oxidation during operation, improves electrical contact and significantly increases the service life.
The design and technical parameters, overall and installation dimensions of PPNI fuses and holders meet modern IEC and GOST standards and therefore allow to replace similar devices both domestic and imported.
