FAQ
Q1: Does 80℃ rating allow continuous 80℃ non-stop operation?
A: It is the maximum rated operating point; consistent performance is guaranteed with basic cabinet ventilation.
Q2: Does the low-temperature release reduce normal surge diversion capacity?
A: The mechanism only activates upon module overheating failure, remaining inactive during standard lightning and switching transients.
Q3:Are cooling fans mandatory for high-temperature cabinet installation?
A:Not required for standard enclosures; auxiliary ventilation is recommended for fully sealed zero-airflow cabinets.
