IEC62752 Short Circuit Withstand
Compliance with IEC62752 for short circuit withstand is a function of both
relay design and PCB layout. ZETTLER's relay design and applications
engineering teams have developed a set of applications notes that contain
important design suggestions to optimize the performance of the AZEV132
relay with respect to its short circuit current withstand capability. Please
contact your local ZETTLER relay office for these important application
notes and suggestions.
In addition, as the overall performance depends on multiple factors such as
part arrangement and trace routing, compliance cannot be generically
guaranteed by ZETTLER. We strongly encourage customers to conduct
their own short circuit tests in accordance with IEC62752 in the context of
their individual application design.
