The MITSUBISHI ELECTRIC YR-UNAA AC ammeter with selector switch displays current for each phase of a three-phase circuit using a single meter. The built-in switch selects which phase is shown, reducing panel space and wiring. It is connected through current transformers with a 5A secondary and is used on switchboards and distribution panels.
