For current trasformer assisted circuits, the other hand paramount importance perform preliminary shorting prior any circuit opening. The circuit closed and the current flows via the terminal blocks and the plug. CT A N N Normal operation circuits In normal operation, the plug fully inserted. Before extraction fully completed, short circuit established between its two poles.225 3029140000 Application range B 9$ Instrument transformer wiring TTB-Range PUSH connection . Make Before Break (MBB)– circuits Throughout cabinet operational life during assembly verifications, the circuit must be disconnected allow further operations. 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. As result the system allows the operator to enjoy redundant Make Before Break contact. The circuit can equally safely and completely opened completing the rotation the lever the left. B. To so, the plug partially extracted from the terminals.
