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.
Note 2. The AC coil resistance values are for reference only.
*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. There is no continuous allowance.
