ACCESSORIES 7/9

Plug-in and withdrawable versions
The fixed part of the plug-in and withdrawable versions of the XT1, XT2, XT3 and XT4 circuit-breakers are
normally supplied with extended front terminals (EF) or horizontal/vertical rear terminals (HR/VR).
The terminals are factory-mounted in the horizontal position. If needed, the customer can easily rotate
the terminals into the vertical position.
— A fixed part with front terminals (EF) can be converted into a fixed part with rear terminals (HR/VR) by
Fixed part adapters
ordering the appropriate terminal kit.
The fixed part of the plug-in and withdrawable versions of the XT5 and XT6 circuit-breakers can be acces-
sorized directly when ordering with extended front terminals (EF) or horizontal/vertical rear terminals
(HR/VR), that can be different from the top and bottom terminals.
The terminals are factory-mounted in the horizontal position. If needed, the customer can easily rotate
the terminals into the vertical position. For the XT5 630A and the XT6 fixed part, the HR and VR terminals
are different and not interchangeable.

The fixed parts can also be fitted with the same types of terminals available on the fixed circuit-breaker
after an adapter has been installed on the terminal area of the fixed part itself. Consequently, the fol-
lowing types of connection terminals are also available for the fixed part:
• extended spread front (ES);
• for copper-aluminium cables (FCCuAI);
• for copper cables (FCCu);
• for flexible busbars (FB);
• multi-cable (MC).
The adapter reproduces the terminal area of the fixed circuit-breaker. This means that the fixed parts
can also be equipped with the same terminal covers and phase separators as those used for fixed cir-
cuit- breakers. 07
In order to mount terminals on the adapter, the front terminals "F" kit provided with the CB is needed.
