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 AC coil resistance values are for reference only.

          3. Performance characteristic data is measured at a coil temperature of 23°C.

          4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of 23°C and not continuously.

          5. The AC power consumption is measured at 60 Hz.

Note: 1. The data shown above are initial values.
           2. The contact resistance was measured with 0.1 A at 5 VDC using the voltage drop method.

           3. The operate time was measured with the rated voltage imposed with any contact bounce ignored at an ambient temperature of 23°C.

           4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric strength.

           5. The electrical endurance was measured at an ambient temperature of 23°C.

           6. This value was measured at a switching frequency of 60 operations per minute. The value in parentheses is for the cased model.
