2.0 Theory of Operation

Theory of Operation
The DCX disconnect product family includes multiple amperage ratings and installation mounting schemes to provide a
DC or Battery source disconnect device for use in Telecom +24 or -48VDC systems as well as solar-alternate energy
or other DC applications. The primary application for the DCX system is to provide over-current protection for battery
sourced equipment and wiring. The secondary function is to provide a service disconnect in order to maintain batteries or
to shut down the battery source connection in an emergency.
