Notes:

1. The coil current ranges is ± 15% for AC (60 Hz), ± 10% for DC (20 ° C 68 ° F).

2. These relays are applicable to a r ange of 80% to 110% of the nominal coil voltage.
However , it is recommended that the rela y be used in a range of 85% to 110% of the
nominal coil voltage, taking the temporary voltage variation into consideration. For
AC types, when operating voltage is 70% of nominal coil voltage, "buzzing" will oc-

cur, and a large amount of current will flow, burning the coil.

3. Each coil resistance of DC types is the measured value at coil temperature of
20 ° C 68 ° F. Please compensate the coil resistance by ± 0.4%, each time the coil tem­perature changes by ± 1 ° C.
