■ Characteristics

Note: 1. The data shown above are initial values.

2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.

3. The set or reset 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.
