Note 1. Industrial Relays, 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. (The AC rated current is the same value for both 50 and60 Hz.)
Note 2. The coil inductance shown is a reference value.
*The figures for the operating characteristics are for a coil temperature of +23°C.
Note 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.
Note 5. The "to" (for example "100 to 120") represents the range of rated voltages.
