    Earth leakage protection relay CONNECTION DIAGRAMS Connection of CBS-4/CBS-4C circuit breaker elements with current shunt coil. In the event of an earth leakage relay trip due to a fault, test or error of the earth leakage current transformer. See cause of the tripped channel on the red display. Rearm the circuit breaker element.
  • Page 10 Earth leakage protection relay Connection of the CBS-4/CBS-4C circuit breaker elements with the current undervoltage coil. In the event of an earth leakage relay trip due to a fault, test or error of the earth leakage current transformer. For connections via the current undervoltage coil, you need to activate the positive safety. More information about this on page 12.
