Suitable for use on a circuit capable of delivering not more than 65 000 rms symmetri-
cal amperes when protected by fuses, inverse time circuit breakers or type E combina-
tion motor controllers as described in the tables below.
Max. voltage is limited to 240 V (230 V units only) or 500 V (400 V units only).
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes (US) or Canadian Electrical Code, Part 1 (CA).
WARNING - The opening of the branch-circuit protective device may be an indication
that a fault current has been interrupted. To reduce the risk of fire or electric shock,
current-carrying parts and other components of the controller should be examined and
replaced if damaged. If burnout of the current element of an overload relay occurs, the
complete overload relay must be replaced.
ATTENTION - LE DÉCLENCHEMENT DU DISPOSITIF DE PROTECTION DU CIR-
CUIT DE DÉRIVATION PEUT ÊTRE DÛ À UNE COUPURE QUI RÉSULTE D'UN
COURANT DE DÉFAUT. POUR LIMITER LE RISQUE D'INCENDIE OU DE CHOC
ÉLECTRIQUE, EXAMINER LES PIÈCES PORTEUSES DE COURANT ET LES AU-
TRES ÉLÉMENTS DU CONTRÔLEUR ET LES REMPLACER S'ILS SONT ENDOM-
MAGÉS. EN CAS DE GRILLAGE DE L'ÉLÉMENT TRAVERSÉ PAR LE COURANT
DANS UN RELAIS DE SURCHARGE, LE RELAIS TOUT ENTIER DOIT ÊTRE REM-
PLACÉ.
For maximum branch circuit protection see tables below.
