The circuit-breakers in fixed version and the fixed part of withdrawable circuit-breakers are equipped with
only)
a 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.
Alternatively, no connection will be required if circuit-breaker frame continuity with the switchgear
earthing is provided by the metal contact (support) between the circuit-breaker and the metal structure
of the switchgear (or a part of the protection circuit) (as long as there are no insulating panels between
the circuit-breaker and the metal frame of the switchgear).

The following layout is also available
Phase barriers are mandatory for 2ps configuration. For the 4ps configuration it is possible to place
isolation 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.
