Flange handle Installed on the panel door. It allows fixed circuit breakers to be operated in accordance with NFPA and UL508A Standards by means of cables of different length, which act on a base installed on the front of the circuit breaker. Two different versions of handles are available in order to fully meet the Standard prescrip- tions required by the application. NFPA handle Thanks to this handle mounted on the shaft of the RHE mechanism, the operator is allowed to operate the circuit breaker and to lock it in OFF position by means of an embedded padlock device also in case of panel door open, as prescribed by the Standards NFPA 79 and UL508A.

Front for the lever operating mechanism This device can be installed on the front of the circuit-breaker and for withdrawable circuit- breakers inside switchboards, it allows the IP40 degree of protection to be maintained for the whole insulation run of the circuit-breaker. It is always fitted with a compartment door lock and with a slot for a padlock device in the open position (0.236in Ø stem up to three padlocks - not supplied) which prevents closing the circuit-breaker and the compartment door. The front for the lever operating mechanism can only be installed on the XT2, XT4, XT5 and XT6 circuit- breakers. The front for the lever operating mechanism can be fitted with a wide range of key locks and padlocks (see the Chapter "Safety and Protection" - section "Locks"). The use of the front for the lever operating mechanism is an alternative to the motor operator and to all of the front type accessories. Toggle extension for XT5-XT6 This device can be used to easily operate the toggle of the circuit-breaker, during manual closing and open- ing operations. The device is removable and does not need screws in order to mount and operate it.
