NOTES
1. The range of coil current for AC relay is
ﾂｱ
15% (60
Hz). For DC relay it is
ﾂｱ
10% at 20
ﾂｰ
C
68ﾂｰF
.
2. The JA relay will operate in a range from 80% to
110% of the nominal coil voltage. It is however, recom-
mended that the relay be used in the range of 85% to
110% of the nominal coil voltage, with the temporary
voltage variation taken into consideration.
3. When the operating voltage of AC relays drops be-
low 80% of the nominal coil voltage. The relay will gen-
erate a considerable amount of heat which is not
recommended for maximum efｬ…iency.
4. The coil resistance of DC types is the measured val-
ue of the coil at a temperature of 20
ﾂｰ
C (
68
ﾂｰ
F
). If the
coil temperature changes by
ﾂｱ
1
ﾂｰ
C. The measured val-
ue of the coil resistance should be increased or de-
creased by 0.4%.
