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.

Note:
1. The above values are all initial values.
2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
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.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
