Characteristics
Note:
The values given above are initial values.
*1.
The contact resistance was measured for 1 A at 5 VDC using the voltage drop method.
*2.
The operate time was measured with the rated voltage imposed and any contact bounce ignored at an ambient temperature of 23
°
C.
*3.
The insulation resistance was measured with a 500-VDC insulation resistance tester at the same places as those used for checking the
dielectric strength.
*4.
The electrical endurance was measured at an ambient temperature of 23
°
C.
