A safety PLC differs from conventional PLCs in that it needs to be certified for safety by a third-party professional organization and meet stringent international standards for safety and reliability. There is a need for a thorough systematic approach to the planning and testing of safety PLCs. TUV*** in Germany and FM*** in United States ...

First of all, both are low-voltage circuit breakers (below 1000V) Let's start with Schneider Masterpact, which is a structural circuit breaker. The current rating of the structure varies from 800A ---- 6300A. The Masterpact series is divided into M series and MT series. The M series has been on the market since 1986 and was screened and delisted in 2002.
