ACCESSORIES 7/7

Withdrawable circuit-breaker
When withdrawable circuit-breakers are used, the codes of the electrical accessories specifically de-
signed for this version must be ordered. These dedicated codes include the wired electrical accessory
with a connector for the moving part and for the fixed part to be inserted on the side of the fixed part.
If the MOE motor operator is ordered, connectors for the fixed part and moving part are always sup-
plied since there is no dedicated code for the withdrawable version. This type of connection allows the
— auxiliary circuits to be disconnected automatically when the circuit-breaker is withdrawn from the
Cabling of withdrawable fixed part. If cabling of the fixed part is required before wiring the moving part, the fixed part
versions
mounting connectors can be ordered as spare parts.
XT7 and XT7 M
Two different areas for the auxiliary connection terminal boxes can be clearly identified on the top of
the XT7 and XT7 M circuit-breakers:
• The terminal area housing the terminals for wiring the auxiliary connections. The terminals can be
wired first and then installed in the circuit-breaker terminal box, thereby facilitating cable connection
for the operator;
• The cartridge modules area, housing the Ekip modules. These are installed directly on the upper part
of the circuit-breaker without removing the Ekip electronic trip unit, thereby minimizing the time re-
quired for the installation and commissioning of accessories.
These areas are the same also in case of withdrawable versions.
Bracket for fixing on DIN-rail
This is a support designed to be installed on the back of the circuit-breakers to simplify assembly on
standardized DIN EN 50022 rails.
The following circuit-breakers can be installed on the DIN EN 50022 rail: 07
• XT1, XT2, XT3 and XT4 circuit-breakers in the fixed 3-pole or 4-pole versions;
• XT1, XT3 circuit-breakers equipped with RC Sel 200; RC Inst, RC Sel for XT1 and XT3 residual current
releases.

Motorizable version
The XT7 M can be equipped with a spring charging motor. To allow complete remote control with the XT7 M,
the circuit-breaker must be fitted with:
• A shunt opening release (YO)
• A shunt closing release (YC)
• A spring charging motor (M)
