Logic discrimination LV  MV Masterpact  Sepam Sepam series 10 Logic discrimination LV  MV Masterpact  Sepam Schneider Electric - Power - Sepam series 10 - April 17th 2018

Bloc diagram Logic discrimination can be achieved between low voltage circuit breaker fitted with Micrologic trip unit and Sepam series 10, 20, 40, 60 or 80 A Restraint Interface Module (RIM) and an auxiliary relay are needed on Micrologic to convert static output to a contact free of potential Schneider Electric - Power - Sepam series 10 - April 17th 2018

Which discrimination ? Short delay and ground protections (and only these protections) from Micrologic will activate the blocking order Overload or long delay Short delay Instantaneous Schneider Electric - Power - Sepam series 10 - April 17th 2018

Which discrimination ? Other curves (long time or overload) must be set for Current or time based discrimination Schneider Electric - Power - Sepam series 10 - April 17th 2018

Curve setting on Sepam Logic discrimination principle remains the same as between Sepam Due to Micrologic, RIM and Sepam behavior, the over current delay must be : For direct time curve : ≥ 80ms (100ms recommended) For IDMTL curve : T at maximum Isc ≥ 80ms Schneider Electric - Power - Sepam series 10 - April 17th 2018
