Ratings and Specifications
Ratings
Operating Coil
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of
+15%/
− 20% for AC rated current and ±15% for DC coil resistance.
2. The AC coil resistance and coil inductance values are reference values only.
3. Operating characteristics were measured at a coil temperature of 23°C.
4. The maximum voltage capacity was measured at an ambient temperature of 23°C.
*1. There is variation between products, but actual values are 80% max.
To ensure operation, apply at least 80% of the rated value
*2. There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC.
To ensure release, use a value that is lower than the specified value.
Contact Ratings
* This value was measured at a switching frequency of 120 operations per minute.
* With no icing or condensation.
