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 inductances shown above are reference values.
3. Performance characteristic data are measured at a coil temperature of 23°C.
4. The maximum allowable coil voltage refers to the maximum value in a varying range of operating power
voltage, measured at ambient temperature 23°C.
5. The "to" (for example "100 to 120") represents the range of rated voltages.
