NOTES
1. The range of coil current for AC relay is ±15% (60 Hz). For
DC relay it is ±10% at 20°C.
2. The JA relay will operate in a range from 80% to 110% of
the nominal coil voltage. It is however, recommended that the
relay be used in the range of 85% to 110% of the nominal coil
voltage, with the temporary voltage variation taken into con-
sideration.
3. When the operating voltage of AC relays drops below 80%
of the nominal coil voltage. The relay will generate a consider-
able amount of heat which is not recommended for maximum
efficiency.
4. The coil resistance of DC types is the measured value of
the coil at a temperature of 20°C (68°F). If the coil tempera-
ture changes by ±1°C. The measured value of the coil resis-
tance should be increased or decreased by 0.4%.
