In Sepam catalog one of the phase current inputs characteristics is "1 second overload". What does it mean? Should it be considered while sizing the current transformers used with Sepam?
Issue:
Customer wants to know what does the below technical characteristic for the current input of Sepam 80 mean
Environment:
Sepam general characteristics
Resolution:
One second overload means the Sepam phase current input can't withstand more than 500A during 1second. If Sepam current input is subjected to a greater value of current, this could destroy the relay. Accordingly, this condition must be considered while choosing the current transformer.
