Replacement (retrofit) of circuit breaker

Replacement of circuit breaker or what is retrofit kit for switchgear from 0.4 and up to 36kV?

Retrofit means the modernisation of switchgear components by replacement of old circuit breakers with new and modern ones without the reconstruction of LV and MV switchgear. The busbars and the switchboard itself remain the same. The major advantages of the retrofit solution is minimum time, effort and costs. The retrofit solution is implemented based on the standard retrofit kit. We will help you to find the right solution out of over 80 standard retrofit kits provided by CopperCube.



3 hours for the replacement of your old circuit breaker
The components of the retrofit kit are manufactured prior to installation thus taking only 3 hours to complete the works. Cable works associated with high costs and effort may lead to damage of isolation and extensive reconstruction works – these are not necessary with the retrofitting solution.


Save up to 80%
With retrofit you save up to 80% of costs comparing to purchase of a new switchboard. This applies also for the costs of devices and installation works. No high one-time costs since the works are carried out step by step which allows gradual investments.


Uninterrupted production and replacement made easy
Retrofit allows you gradual replacement of circuit breakers. There is no need to stop production and to cut off power for all switchboards. The works can be carried out step by step for every single switchboard.


Participate in sustainable development
The retrofit solution complies with the concept of sustainable management. There is no need for complete reconstruction of the switchgear since retrofit extends the useful lifespan, which allows to minimize the use of resources, amount of waste and energy consumption.



The retrofit solution for the replacement of circuit breakers is based on the standard retrofit kit. It consists of the new modern circuit breaker, frame or chassis, isolators and steelwork and can be installed according to installation manual. The components of the retrofit kit match the dimensions of the frame and busbars and thus enable the installation without modifications to design of the switchboard.
