*All models are certified by UL, CSA, and TÜV.
Note: 1. The applicable load is the value for when the SSR is used with silicon grease applied to the specified heat sink. The
applicable load depends on the ambient temperature. Refer to Load Current vs. Ambient Temperature in
Engineering Data on Data Sheet.
2. Loss time increases under 75 VAC. (Refer to Data Sheet.) Confirm operation with the actual load.
