The FT-21 switchboard meter is built into the Flexitest™ relay enclosure. This consists of a panel-mounted housing with all necessary power and control terminals on the rear of the enclosure; plus a drawout mounting cage for the meter electronics.
The complete meter chassis is mounted on a drawout assembly and all connec - tions are made when the drawout chassis is inserted into the panel-mounted enclosure. Following assembly, an appropriate meter chassis with the desired features, may be inserted into the housing and connected in a matter of moments. Current transformer switches are self-shorting when the CT disconnect switch is opened.
