ABB Retrofitting kit
Direct Replacement New Emax moving portion in Old Emax Fixed Part.
With no modifications to be made to your existing switchgear, retrofitting kits are a cost effective solution to upgrade your electrical system. The direct replacement retrofitting kit allows a very fast and reliable upgrade of the old Emax to New Emax Range.
In the field of low voltage circuit-breakers, ABB ensures operating continuity between the previous series of its apparatus and those currently in production, by studying special solutions to replace old breakers with new ones, with minimal disruptions to the existing system.
It is now possible to replace the old series of Emax circuit breakers, from E1 to E6, in withdrawable version with the recent series of circuit New Emax by using the newly designed direct replacement retrofitting kit.
A dedicated moving part has been created starting from the new circuit breaker in order to replicate the main and auxiliary circuit of the Old Emax.
The result is a new New Emax moving part able to be inserted into the existing old Emax fixed part, maintaining the original connections in the switchgear.
With this solution, there is no need to manage any dismantling operation of the existing fixed parts of the Emax breakers: thanks to this special solution the downtime is reduced and limited to the single load.
