Circuit Breakers – Retrofit
Replacing old circuit breaker components with newer versions can be done using the ABB special conversion kits which enable quick installation without structural modifications to the original compartment.In addition complete “turnkey” solutions are available. Specific conversion kits have been developed in order to replace old components with new ones that can be found in the newest circuit-breakers.
DEFINITION
Exchange of ware parts or outdated equipment components while maintaining original plant and equipment configuration. The replacement of legacy with new active components. The main purpose is to improve the life cycle status of the circuit breaker.
There are 3 different types of retrofit solution available.
-
Hard bus Retro fill (RF)
The obsolete circuit breaker is totally removed and substituted with the new circuit breaker. The kit contains special designed and preconfigurated bus bars and covers to adapt the new Circuit breaker to the existing bus bars. -
Cradle in Cradle (CiC)
The fixed part of the new circuit breaker is suitably adapted and tested in ABB. This solution allows the new fixed part be fast fitted inside the existing fixed part. -
Direct Replacement (DR)
It is the faster solution for the customer: the moving part of the old circuit breaker is removed and the moving part of the new circuit breaker is suitably modified and tested in ABB to be inserted into the existing fixed part. This implies very short plant shutdown of the single user.
BENEFIT
The conversion kit solutions improve the safety and the reliability of your plant, excluding the need for expensive spare parts and lowering maintenance expenses.
The use of ABB Breakers Service conversion kits provides the following benefits:Improves the safety and the reliability of a plant, excluding the need for expensive spare parts and lowering maintenance costs.
- Reduction in cost compared with those needed to install completely new switchboards.
- Reduced assembly operation times and the possibility of spreading installation stoppages out over time, which increase the guarantee of service continuity.
- Reduction in maintenance and repairing costs
- Components replaced quickly, easily and safely
- Little or no hardware modifications.
- Adaptation plugs for auxiliary applications.
- More control on the plant with new protection relays.
