People Electric · AC Contactor
Product overview
Original People Electric CJX1 AC contactors remotely connect and break AC circuits and can be combined with a correctly matched LRS2 (3UA) overload relay in an electromagnetic starter. The documented range extends from 9 to 400A in AC-3 duty at 380V. Ratings at 660V and in AC-4 duty differ; select the contactor for the actual load and voltage.

Current buttons refer to AC-3 at 380V. The coil choices retain the paired voltage designations printed in the manufacturer 50/60Hz table; specify the operating frequency and confirm the actual coil nameplate with the quotation. The DC-13 ratings in the catalogue concern auxiliary-contact switching and do not establish a DC-coil option. Default auxiliary contacts are 2NO+2NC; 3NO+3NC and 4NO+4NC are documented only above 32A. A 475 frame appears in dimension drawings but has no main technical-rating column here and is not selectable. Series photographs can show different frame sizes. The 127V coil pair is withheld: the main technical paragraph prints 127/152V while the ordering table prints 127/171V.
Typical applications
- Remote AC motor and distribution-circuit switching within the matching duty ratings.
- Electromagnetic motor starters with a correctly selected overload relay.
