One of the most ingenious retrofit sets ever have been placed by the subway of Frankfurt in Germany.
4 breakers has been changed in the installation that provides the power for the air conditioning systems of the Frankfurt Subway Headquarters.
The CBS team retrofitted old Klöckner Moeller NZM22 (2X 800A) to a new Schneider Electric MTZ1 1600A.
The difficult part was to go from 6 poles connection with the old breakers to 3 poles in the new breakers in this retrofit unit .
The change was a success and was carried out in 4 hours per breaker.
