Generals The RC223 residual current release, which can be combined with the Tmax T3, T4 four-pole circuit-breakers in the fixed or plug-in version, is the most advanced solution in the whole residual current release family for the Tmax range. Apart from the signals and settings typical of the basic residual current release, RC223 also allows the selection of the maximum threshold of sensitivity at the...
