Main advantages Why a retrofit solution? Retrofit means upgrading existing system with modern components, in order to optimize all technical, safety economic and ecological concerns With the retrofit solution, you can exchange just the components that have been subjected to the most wear over their many years of reliable operation The result of retrofit solution is a major improvement in reliability, safety, maintenance reduces and performance Retrofit is ideal solution to ensure the optimum return on investment December 3, 2013 Slide 3 1HC0088406 E01 AA
Costumer benefits (I) Reliability Significant life time extension Lower maintenance requirements Long term availability of spare parts Safety Strong fault risk reduction Additional embedded safety features Improved operator protection Technology Latest generation of circuit breaker Upgrading of technical ratings Designed according latest IEC & ANSI Standards Factory tested product December 3, 2013 Slide 4 1HC0088406 E01 AA
Costumer benefits (II) Project execution Short implementation time for replacement Minimum shutdown of the switchgear Smooth site activity Investment Limited capital investment Minimization of further maintenance costs Warranty for retrofit components Retrofit improves the availability and realibility of your installations in the most cost-effective way December 3, 2013 Slide 5 1HC0088406 E01 AA
