Earthing (for E2.2-E4.2-E6.2 The circuit-breakers in fixed version and the fixed part of withdrawable circuit-breakers are equipped with a
only) screw for the ground 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, tighten the screw with a torque of 2 N m - 17.7 lb in.

Phase separators (for E2.2- Phase barriers are mandatory for 2ps configuration. For the 4ps configuration it is possible to place isolation
E4.2-E6.2 only) barriers for the segregation of live parts.In addition, the phase separators are mandatory:
• If, between two phases, the minimum distance between the screws that fix the circuit-breaker terminals
to the connection bars is less than 14 mm - 0.55".
• For circuit breakers version IEC >690V and UL >635V.
Information on the assembly is available on the website http://www.abb.com/abblibrary/DownloadCenter/, in
particular with the kit sheet 1SDH001000r0810.
