What is circuit breaker control and how is it enabled?

Circuit breaker control is a function available on the Sepam series relays to enable the remote opening and closing of circuit breakers. To enable circuit breaker control, connect to the Sepam relay using SFT2841 and access the program logic screen. The function is labeled CB Control, here it may be enabled or disabled as needed. When this function is enabled I11 and I12 are automatically locked into being the open and closed status contacts from the breaker. If these contacts are not connected when CB control is enabled the relay will return a Trip Circuit Fault.
