– Segregation plates and separator plates
The rear part of the circuit-breaker has been designed with specific slots in which
insulating walls can be housed to facilitate segregation of live parts. In addition,
phase separators are available as an optional accessory for E1.2.
Earthing connection
To achieve continuity and equipotentiality of earthing between the Emax 2 circuitbreaker and the protection citcuit of the switchboard, customers can do either of
the options below:
– Connect the Emax 2 fixed circuit-breaker or the fixed part of the withdrawable
circuit-breaker to the protective circuit by means of a cable with suitable crosssectional area to fulfil the requirements of clause 10.5.2 fo the Standard IEC
61439-1.
– If the continuity of the circuit-breaker frame with the switchboard earthing is
guaranteed by the metal contact (support) between the circuit-breaker and
the metal structure of the switchboard (which is a part of the protective circuit)
no connection is necessary (provided that no panels of insulating material are
interposed between the circuit-breaker and the metal frame of the switchboard).
Emax E1.2, fixed version, does not require any earthing connection

Busbar types
The circuit-breakers, via the terminals, can be connected to the main distribution system by busbars of different types: copper,
silver-plated copper and tinned aluminium when the main distribution system is made of aluminium.
The circuit-breakers can be connected directly with copper or aluminium cables in the case of E1.2 circuit-breakers, or
indirectly by cable-carrying bars in the case of E2.2, E4.2 e E6.2.
Accessories
The SACE Emax 2 circuit-breakers offer a wide range of accessories that improve safety levels for technicians working on the
switchgear and circuit-breakers. Furthermore, thanks to the different types of mechanical interlock available, pre-determined
coordination strategies can be achieved between the circuit-breakers. In detail:
– Horizontal and vertical interlocks between circuit-breakers
– Door lock with circuit-breaker in closed position
– Switchgear door lock in racked-in/out position
– Lock of racked-out mechanism with door open
– External lock of shutters
– Flange for switchgear door IP30 and IP54
