Distribution points of PR-11 series
Distribution cabinets (points) PR are designed for receiving and distributing electrical energy in power and lighting AC circuits rated up to 660 V inclusive, protecting outgoing lines against overload and short-circuit currents, and for infrequent switching of electrical circuits (up to six times per hour).
The rated current of the cabinet and circuit breakers on outgoing lines is reduced by 10% for cabinets with IP21 enclosure protection degree and by 20% for cabinets with IP54 enclosure protection degree.
Busbars allow short-circuit peak withstand current at cabinet rated currents: 160, 250, 400 A - 25 kA; 630 A - not less than 50 kA.
In terms of technical and safety requirements, PR comply with the GOST 22789-94 standard applicable in the Republic of Kazakhstan.
