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 range of 80% to 110% of the nominal coil voltage.
However, it is recommended that the relay 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
occur, 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.

occurs. When used in such applications,
mount the relay so that this force does
not parallel the direction of contact
