Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and
flame. The devices are intended for protection against occasional over-current or over temperature fault conditions and
should not be used when repeated fault conditions or prolonged trip events are anticipated. Device performance can be
impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical
procedures for electronic components.
