Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of ±10%.
2. Operating characteristics are measured at a coil temperature of 23°C.
3. Max. permissible voltage refers to the maximum value in a varying range of operating power voltage, not a continuous voltage.
