Residual current protection

The fixed version of the RC Sel residual current release can be easily converted:
• into a plug-in type of release:
- by ordering the kit for converting the residual current release from the fixed to the plug-in version
• into a withdrawable type of release:
- by ordering the kit for converting the residual current release from the plug-in to the withdrawable
version. This kit contains the shunt opening release of the withdrawable residual current device to
replace the shunt opening release supplied with the fixed version. The shunt opening release of the
withdrawable residual current device contains both the connector for the moving part and the
connector for the fixed part.
With the RC Sel residual current release for the XT2-XT4, it is possible to use the same terminals for the
fixed circuit-breaker and for the fixed parts of the plug-in and withdrawable circuit-breakers.
With the withdrawable and plug-in versions, frame 160A with RC can be used up to a maximum current of
135A, whereas frame 250A can be used up to 210A.
