R1448NS18H can be used instead of R1448NS14H (D450SH14 F2KO/D450CH14 F2KO) as mechanically equivalent and electrically superior.

R1448NS18H has the same fit form and function and a higher amperage to the following westcode ranges R1446NS (R400SH/R400CH); R1331NS (D450SH/D450CH); R1280NS (D390SH/D390CH); R1279NS (D391SH/D391CH); R1275NS (R395SH/R395CH); R1271NS (R355SH/R355CH); R1178NS (R325SH/R325CH); R1158NS (D350SH/D350CH); R1127NC (D315CH); R1124NS (R305CH/R305SH) however the voltages and tq’s will differ so please check carefully.

The following devices are physically identical, but mechanically superior, to R1448NS18H  and can be used instead: R1448NS20H;

R1446NS12E may be used in place of Ansaldo device ATF524; SPCO device C458;
Estel devices TF153-1250; TF253-800; TF253-1000; TFI253-800; TFI253-1000
And Powerex device T9GH1810. Please cross reference with datasheets; contact us for westcode data sheet.
