each model. Use function codes F10 to F12 to set the protection level.
2. Short circuit rating
Suitable for use on a circuit capable of delivering not more than 10,000 rms symmetrical amperes, 480
Volts maximum when protected by circuit breaker having an interrupting rating not less than 10,000 rms
symmetrical amperes, 480 Volts maximum. Models FRN: rated for 400 V class input.
CONVIENT AUX CIRCUITS NON SUSCEPTIBLES DE DÉLIVRER PLUS DE 10,000 AMPÈRES
SYMÉTRIQUES EFF., MAXIMUM 480 V
Branch Circuit Protection must be provided by the end user, sized per the Canadian Electrical Code, Part
I, the National Electrical Code and all applicable local codes.
INTEGRAL SOLID STATE SHORT CIRCUIT PROTECTION DOES NOT PROVIDE BRANCH CIRCUIT
PROTECTION. BRANCH CIRCUIT PROTECTION MUST BE PROVIDED IN ACCORDANCE WITH THE
CANADIAN ELECTRICAL CODE, PART I.
LA PROTECTION INTÉGRÉE CONTRE LES COURTSCIRCUITS N'ASSURE PAS LA PROTECTION
DE LA DÉRIVATION. LA PROT
ECTION DE LA DÉRIVATION DOIT ÊTRE EXÉCUTÉE
CONFORMÉMENT AU CODE CANADIEN DE L'ÉLECTRICITÉ, PREMIÈRE PARTIE.
