Contact Specifications
*1
This value is a reference value in the resistance load. Minimum capacity changes depending on the switching frequency, environment temperature,
and load.
*2
Rise time: 10 µs; decay time to half crest: 160 µs.
*3
This shows the number of operations with fatal defects. Stable characteristics are maintained for 1 x 10
7
operations.
