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. (The values given for AC rated current apply at 50 Hz or
60 Hz.)
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. The maximum voltage is one that is applicable to the Relay coil at 23°C.
for AC rated current and ±15% for DC coil resistance. (The values given for AC rated current apply at 50 Hz or
60 Hz.)
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. The maximum voltage is one that is applicable to the Relay coil at 23°C.

*3. The operate and the release times were 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.
