Input and input-registration boards (IB and IRB)

Input and input-registration boards  (IB and IRB) are designed to receive and monitor the  AC electricity (only IRB) of systems with the earthed neutral.
The boards are designed for installation in industrial, public, municipal and other objects of energy supply. The metal structure consists of one or more frames, connected in line, on which various panels and doors are established.
  
Functional unit is based on a switching device and includes:
• mounting plate to install apparatus;
• front panel, preventing direct access to live parts.
Cabinets are made as floor-based type. Cabinet design provides input and output of feed and waste lines both above and below.

The treatment of cabinets is made by cathaphoresis method with addition of a layer of thermosetting epoxy-polyester powder paint, color: white RAL 9001.
All design elements and functional blocks are designed and tested taking into account the performance specifications of switching devices. This provides reliability of electrical device operation and optimum security for staff.
