IEC 62752 / IEC 62955 Short Circuit Withstand
Compliance with IEC 62752 or similar standards 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 AZEV140 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 IEC 62752 or similar
standards in the context of their individual application design.
