Execution and installation

Conversion kits
The following conversion kits can be ordered for the different versions. This is applicable the whole Tmax
XT family, up to Tmax XT6.

• Kit for converting a fixed circuit-breaker into the moving part of plug-in/withdrawable versions
The conversion kit converts a fixed circuit-breaker into a moving part of the plug-in/withdrawable
versions. When withdrawable versions are required, it is essential to order an accessory for the front of
the circuit-breaker to maintain the IP40 degree of protection along the entire insulation run. This ac-
cessory is made of the following options:
—
Conversion kit for - front for the lever operating mechanism (FLD);
converting a fixed - motor operator (MOE);
circuit-breaker into
the moving part of a - direct or transmitted rotary handle operating mechanisms (RHD or RHE).
plug-in circuit-breaker In the case where no accessory to be applied onto the front is indicated, the front for the lever oper-
ating mechanism (FLD) is automatically included in the order.

• Kit for converting a fixed part of a plug-in version into the fixed part of withdrawable versions
The kit comprises:
- a guide for transforming the fixed part of the plug-in circuit-breaker into a fixed part of a with-
drawable circuit-breaker;
— - a racking-out lever that allows the moving part to be inserted and withdrawn. The mechanism allows

circuit-breaker.

• Kit for converting a fixed circuit-breaker into the plug-in version for RC Sel residual current devices
for XT2-XT4-XT5
The RC Sel 4-pole residual current devices for the XT2, XT4 and XT5 can be converted from fixed ver-
sions to plug-in versions using the special kit.

mechanism or the direct rotary handle, thus allowing the use of residual current devices.
In the plug-in to withdrawable conversion kit, there are also PIN connectors to be applied onto the
right side of the circuit-breaker to facilitate disconnection of the auxiliary circuits connected to the
residual current device.
For the XT1, XT2, XT3 and XT4, this kit also contains the opening solenoid of the residual current de-
vice dedicated to the withdrawable version, which is fitted with a connector for the fixed part and the
moving part.
