Notes:

1.Coil resistance varies ±10% for less than 1,000 W, and ±15% for more than 1,000 Ω. For each ±1°C change in ambi-

ent temperature, coil resistance varies

±0.4%.

2.For each ±1°C change in ambient tem-

perature, pick-up and drop-out voltages vary approximately ±0.4%.

3.Pick-up and drop-out voltages are measured with the relay mounted as follows.

4. The coil operating current should be pure direct current in principle. When rectified alternating current is applied to the coil, the relay characteristics (pick-up, drop-out voltage) may be changed due to the ripple factor. Confirmation of the characteristics in the actual circuit is suggested.
