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 inductance values are reference values only (at 60 Hz).

         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% maximum.

     To ensure operation, apply at least 80% of the rated value (at a coil temperature of 23°C).

*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.

Note: 1. The rated current for AC is the value measured with a DC ammeter in half-wave rectification.
         2. 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.

         3. The AC coil resistance is a reference value only.

         4. Operating characteristics were measured at a coil temperature of 23°C.

         5. The maximum voltage capacity was measured at an ambient temperature of 23°C.

*There is variation between products, but actual values are 80% maximum.
