Do SSR relays withstand abrasion?

Unlike mechanical relays that may result in contact abrasion, the SSR will provide good performance as long as the surge current is no higher than half of the surge withstand current. If the SSR is in continuous ON/OFF operation and a current exceeding the rated value flows frequently, however, the SSR may overheat and a malfunction may result.
