Note 1. The rated current and coil resistance were measured at a coil temperature of 23°C with tolerances of ± 10%.
Note 2. The operating characteristics are measured at a coil temperature of 23°C.
Note 3. The maximum permissible voltage is the maximum value of the fluctuation range for the Relay coil operating power supply and was measured at an ambient
temperature of 23°C.
