Protection devices Lock for racking-out mechanism with circuit- breaker in closed position (Fig. 14)
All SACE Emax 2 withdrawable circuit-breakers are always supplied with a lock that prevents the mobile part from being racked in and racked out when the circuit- breaker is in the closed position. To rack in the mobile part, the circuit-breaker must be in the open position. Lock for racking in / racking out the mobile part when the door is open - DLR The DLR accessory, which is mounted on the fixed part, prevents the mobile part from being racked in or out when the switchgear door is open. Lock to prevent door opening when the circuit- breaker is in racked-in / test position - DLP (Fig. 15) The DLP safety device prevents the switchgear door from being opened when the mobile part of the with- drawable version of the circuit-breaker is in the racked-in or test position. This accessory can be installed on either the right-hand or left-hand side of the fixed part. It is available for circuit- breakers E2.2, E4.2 and E6.2. If mounted on the right side, it is an alternative to the mechanical interlock, the AUX 15Q or the DLC. Lock to prevent door opening when the circuit- breaker is in the closed position - DLC (Fig. 16) The DLC prevents the compartment door from being opened when the circuit-breaker is in the closed posi- tion (and with the circuit-breaker racked in for withdrawable circuit-breakers). It also blocks the circuit breaker from closing when the compartment door is open. DLC for E1.2 is an alter- native to the mechanical interlock and the AUX 15Q. DLC direct door for E2.2...E6.2 is compatible with me- chanical interlocks type A-B-D and the AUX 15Q. DLC cable door for E2.2...E6.2 is not compatible with me- chanical interlock. DLC cable door for E2.2... E6.2 is compatible with the AUX 15Q. Anti-insertion lock The withdrawable circuit-breakers are equipped with special locks that allow the mobile part to be inserted only into the corresponding fixed part. Mechanical operation counter - MOC (Fig. 17) The number of mechanical operations is often one of the elements that determines the frequency of ordi- nary maintenance operations on circuit-breakers. With this mechanical operation counter, which is always visible on the front of the circuit-breaker, the user knows how many mechanical operations the device has performed.
