It's not sacrificial and can be used more than once. It may not last indefinitely however. It tests itself and gives a status indication. Here is the small print that comes in the package:
"No surge protection device can protect against unlimited surges in either amplitude, power or duration. In certain cases it is possible that the APM will provide protection, but in the process become damaged so that it no longer provides protection. In this event, the APM LED will turn red, and it will begin to give a chirping sound. In extreme cases such as lightning strikes, the APM can be damaged to the point it no longer functions or provides feedback. "
