Storey detection and distribution switchboards (SS)

Assignment
Storey switchboards are designed for receiving, distributing and monitoring (if a meter is available) of AC in power systems with the earthed neutral, to protect lines from overload and short circuit currents and non-permissible leakage currents into the ground (if protective cutout device – PCD – is available), and for placement of devices of radio, telephone and television networks.
 
Design
Metal construction of the storey switchboard is an electrical panel which is built-in in niche of size 950x900x140 mm, and consisting of three compartments:
• input and distributing, where input protection devices and waste lines are placed;
• detecting (monitoring) - to install one (three) phase electricity meters;
• low-current - for placing devices of TV and radio networks, telephone lines, alarm system, intercom systems and video surveillance networks, etc.

Each compartment has an individual door locked. Doors of detecting module have glazed openings to control the indications of meters (as per the number of apartments - 2, 3,4, or 6).
 
The metal construction is covered by reactive powder coating. The color is light gray RAL7035.
