Power conditioners

Eaton’s Current Limiting Reactor (CLR) is a power conditioning system that limits fault current under short-circuit conditions, helping to support overall NFPA-70E and NFPA-75 safety. The CLR is to be installed between a switchboard and switchgear and will be electrically connected to them with flexible busbar connectors.
