Disconnect short circuit circuits To fully allow consequent operations, the plug completely extracted from the base terminals, thus maintaining the previously established short circuit between its poles and subsequently opening the circuit. likewise manner, the same circuit status can obtained by bringing the lever into its middle position. To so, the plug partially extracted from the terminals. Before extraction fully completed, short circuit established between its two poles. CT A N N Normal operation circuits In normal operation, the plug fully inserted. Make Before Break (MBB)– circuits Throughout cabinet operational life during assembly verifications, the circuit must be disconnected allow further operations. As result the system allows the operator to enjoy redundant Make Before Break contact. CT A N N N N CT A N N CT A N N CT A N N CT A Voltage circuits not require special operational safety other than avoiding short circuit the secondary wiring used. The circuit closed and the current flows via the terminal blocks and the plug. B. The circuit can equally safely and completely opened completing the rotation the lever the left. For current trasformer assisted circuits, the other hand paramount importance perform preliminary shorting prior any circuit opening
