Characteristics
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.
