Can CHANCE® fuse links withstand 150% of their rating continuously?

No, the 150% rating is only for special loading situations such as short time overloads and cold load pickups. Every effort must be made to select a fuse link with current rating as close as possible to the expected full load condition of the device it is designed to protect.
