OneFit is the latest ABB hard-bus retrofill design concept, embedding an integrally safe plug-in technology to easily connect the new breaker to a wide range of existing non-ABB panels.
OneFit balances the need for a retrofill solution with reasonably limited site works and linked outage compared to the switchgear replacement.
Retrofill is a modernization process including the replacement of the circuit breaker and main functional components of the original switchgear.
OneFit retrofill solution is composed by an adaptation kit and a standard withdrawable apparatus. This approach allows having benefits both in short and long term perspective:
- equipment and spare parts are interchangeable with new ABB extension panels and additional switchgear
- apparatus are reusable in future ABB replacement switchgear providing an optimized investment to next substation renewal.
OneFit range is composed by four packages at increased technological content targeting personnel safety and switchgear renewal:
- OneFit Safety
- OneFit Safety Plus
- OneFit eSafety Plus
