Purpose
Designed for infrequent (no more than 6 per hour) non-automatic switching of AC electrical circuits with a frequency of 50 Hz, a voltage of 400 V
Application
Input-distribution devices of public and industrial buildings, cabinets and distribution points, transformer substations, control boxes.
materials
Carrier panel and control elements are made of galvanized steel
Current-carrying parts are made of tinned electrical copper
The insulating elements are made of ceramic.
Advantages
Simplicity and reliability of design
Ease of installation
Wide choice of types according to rated current
Design
The main parts of the switches are knives, contact and axial racks mounted on a common plate.
Knife contact system with visible open circuit
The on and off position of the device is indicated by the position of the drive handle
The RP series circuit breakers use fuse links of the PPNN, PPN, PN2 series fuses.
Possibility to change the distance between the jaws of the bases for different types of fuse links.
The design of the contact leads ensures the connection of copper and aluminum conductors and cables terminated with cable lugs and busbars using threaded connections.
All threaded connections of the switches are protected from self-unscrewing.
Operating conditions
The working position of the circuit breakers during operation is vertical, the deviation in any direction is not more than 5 C
Knife switches with side (shifted) drive can be installed horizontally
Ambient temperature from -45 to +40 C
Height above sea level no more than 2000m
Relative air humidity no more than 50% at +40 C or 90% at 20 C
