Earthing (solo E2.2-E4.2-E6.2)
The circuit-breaker in fixed version and the fixed part of withdrawable circuit-breaker E2.2-E4.2-E6.2 are
equipped with a screw for the earth connection.
The connection must be implemented by means of a conductor of suitable cross-section according to the
IEC 61439-1 Standard.
Clean and degrease the area around the screw before making the connection.
After assembly of the conductor, lock the screw with a torque of 2 Nm.

Phase separators (for E2.2-
E4.2-E6.2 only)
Phase separators are available on request only for E2.2-E4.2-E6.2 circuit-breakers; otherwise, it is possible
to position some insulation barriers to segregate live parts. The phase separators are mandatory if, between
two phases, the minimum distance between the mounting screws of the circuit-breaker terminals and the
connection bars is less than 14 mm.
Information on the assembly is available on the website http://www.abb.com/abblibrary/DownloadCenter/, in
particular with the kit sheet 1SDH001000r0810.
