4.1.4 General information, GCLS type series 51
The gear parts of the GCLS can be damaged by ozone concentrations above normal threshold values
(Regulation 2008/50/EC); in particular in the direct vicinity of circuit breakers (ozone formation through
electricarcs), the GCLS may only be used if it is protected accordingly (min. IP54).
