Safety Key lock in open position - KLC (Fig. 10)
Due to these safety devices, the SACE Emax 2 circuit-breaker can be locked in the open position. The lock can also be used during maintenance activities when the accessory cover is removed. The device is avail- able with lock with different keys – KLC-D (for only one circuit- breaker) or with the same keys – KLC-S (for several circuit-breakers). Four different key numbers are available for the KLC-S. SACE Emax 2 also allows an alternative key lock to be installed. The following key lock set-ups are also available: • Ronis • STI • Kirk • Castell For the special ones the key lock must be supplied by the customer. Padlocks - PLC (Fig. 11) * These padlock options allow the circuit-breaker to be kept open by acting directly on the mechanical oper- ating device (opening pushbutton). Three different padlock versions, which are an alternative to the PBC, are available: • Locking device with plastic structure for up to a maximum of three padlocks of 4 mm • Locking device with metal structure for up to a maximum of two padlocks of 8 mm • Locking device with metal structure for one padlock of 7 mm or for padlock holders The padlocks must be supplied by the customer. Key lock in racked-in / test / racked-out position - KLP (Fig. 12) The KLP enables the mobile part to be locked in one of the three positions: racked-in, test and racked-out. It can be supplied with locks with different keys – KLP-D or with the same keys – KLP-S. A second key lock option can be added for a maximum of two key locks per breaker. Locking in the racked-in, test and racked-out positions can be achieved by using other key locks – KLP-A. Adapters are offered for acceptance of Ronis, STI, Kirk and Castell locks, which are to be provided by the customer. With the exception of the Castell version, every circuit-breaker can accept up to two key locks. Locking can be limited to the racked-out position with a supplementary accessory. Padlock in racked-in / test / racked-out position - PLP (Fig. 13) * The PLP can hold up to three padlocks of 8 mm in diameter. The structure housing the padlocks can also be used in combination with the 2 lock KLP keylock option. It also enables the lock of the moving part only in the racked-out position by means of the supplementary lock in racked-out position. Shutter lock – SL When the mobile part is in the test position, the shutters of the fixed part close, maintaining the insulation distance and physically segregating the live parts of the of the cradle from the internal breaker compart- ment of the cradle. Using two dedicated mechanisms, the upper and lower shutters can be locked inde- pendently of one another. The shutter lock is always supplied with the fixed part of the SACE Emax 2 cir- cuit-breakers and locks the shutters, using a maximum of three padlocks of 4 mm, 6 mm or 8 mm. Anti-racking out device / Fail safe - FS The anti-racking out, or fail safe device prevents the moving part of withdrawable circuit-breakers from being racked out of the cradle when the springs are charged. It is always supplied with the moving part of UL circuit-breakers and switch disconnectors. It is an alternative to the undervoltage coil or second shunt coil.
