"Conditions of Acceptability" for SCT1xxx
Conditions of Acceptability
• These devices shall be installed within equipment that will provide an acceptable enclo-
sure.
• The acceptability of the mounting means for these transformers shall be determined in
the end-use application.
• These devices have not been tested for radio influence voltage (RIV), Accuracy and Me-
chanical Tests; Only Temperature tests at 60 Hz and Dielectric Voltage-Withstand tests
have been conducted.
• These devices employ Class 105 (A) Insulation Systems.
• The suitability of the terminal blocks shall be considered in the end product.
• Based on the temperature test results, the transformers may be classified as 55°C rise
type at 55°C ambient
"Conditions of Acceptability" for SCT2xxx
Conditions of Acceptability
• These devices shall be used within the Recognized ratings as indicated.
• Each transformer shall be mounted within equipment that will provide a metal or non-
combustible material enclosure for the transformer.
• The acceptability of the secondary terminals shall be determined in the final application.
• This transformer has not been tested for accuracy, impulse and mechanical tests per
ANSI C57.13 or CSA CAN3-13-M83. Only temperature and voltage withstand tests at 60
Hz were performed.
• These transformers are designated as '55 deg rise transformers', for use in an ambient
shown in the rating table.
"Conditions of Acceptability" for SCT3xxx
Conditions of Acceptability

the end-use application.
• These devices have not been tested for radio influence voltage (RIV), Accuracy and Me-
chanical Tests; Only Temperature tests at 60 Hz and Dielectric Voltage-Withstand tests
have been conducted.
• These devices employ Class 105 (A) Insulation Systems.
• The suitability of the terminal blocks shall be considered in the end product
• Based on the temperature test results, the transformers may be classified as 65°C rise
type at 30°C ambient
