I have read through two international standards relative to the
captioned subject. There are some differences even though they both are
called the same classes.
EN 60 355-1 IEC 85
Class Temp rise Actual temp
A 75 degC 105 degC
E 90 degC 120 degC
B 95 degC 130 degC
F 115 degC 155 degC
H 140 degC 180 degC
Since the readily available enamelled copper wires are largely quoted
American specifications as below, I am seeking some advice how to tie
the American approved/classified wires into European requirements.
UL 506
Class Temp rise
105 70 degC
130 95 degC
155 115 degC
180 135 degC
200 150 degC
220 165 degC
Appreciating any expert advice.
Thanks and regards,
Raymond
