NOTES
1. The range of coil current for AC relay is
±
15% (60
Hz). For DC relay it is
±
10% at 20
°
C 68°F.
2. The JA relay will operate in a range from 80% to
110% of the nominal coil voltage . It is howe ver , recom-
mended that the relay be used in the r ange 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 v oltage. The relay will gen-
erate a considerable amount of heat which is not
recommended for maximum efficiency.
4. The coil resistance of DC types is the measured val-
ue of the coil at a temperature of 20
°
C (68
°
F). If the
coil temperature changes by
±
1
°
C. The measured val-
ue of the coil resistance should be increased or de-
creased by 0.4%.
