PPNI fuse links

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 630A.

PPNI fuse links are used for single and three-phase networks having voltage limited to 660V (50Hz).

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, HD 60269-2.

     Awarded silver medal of the 15th International Exhibition “Electro-2006” in nomination “Best electrical equipment” for high exploitation characteristics and engineering solution ensuring power loss enhancement.

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 630A. 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 +60C. It allows applying PPNI in various climate zones.
  • High breaking capacity: at 660V 50kA, at 500V 120kA.


Low power losses

Using quality contemporary materials and new construction decisions contributes to lowering power losses in PPNI fuse links as compared to PN-2 fuses.

Data indicated in the table reflect the cost effectiveness of PPNI as compared to PN-2.

Energy saving

Efficiency of this new development becomes more visible if we consider not a separate fuse link but an assembled distribution panel. From knowledge that the average cost of electric energy in Russia for people and industries is equal to 3 RUR/kW, we can calculate the cost-effectiveness not only in kW but also in RUR.

If an electrical distribution panel with the outgoing lines per 250A is assembled basing on new PPNI fuse links, the cost-effectiveness will make up 2602 kW or 7806 RUR annually.

Design Features


Fuse link contacts are made of galvanized (tin-bismuth alloy) electrical copper preventing their oxidation in the process of exploitation. Fuse element is made of phosphorous bronze (orichalcum with addition of phosphor) and securely fixed by means of spot welding with fuse terminals.
Receptacle base (insulator) is made of reinforced thermosetting plastic resistant to corrosion, mechanical impact, differential temperature and impact blows arising at short circuits up to 120 kA. There is a special indicator introduced into the fuse element construction executed in the form of a retractable rod providing for visual determining the tripped fuses.
Fuse element contacts are executed in the form of a knife (sharpened) that provides for facilitating their installation in the receptacles. PPNI fuse links have their breaking capacity lying within the whole gG range allowing ensuring protection of electric installations from short circuits and overloads.
All dimensions of PPNI fuse elements are easy to install or dismount using a universal RS-1 removal handle. The handle’s insulation sustains voltage up to 1000V. Construction, technical features, overall and installation dimensions of PPNI fuse elements and receptacles correspond to contemporary GOST and IEC standards allowing superseding comparable devices both of local and foreign manufacture.
In order to ensure easy and efficient arc extinguishing, the body of a fuse element is filled with highly chemically purified quartz sand.
