Recommendation for best usage: in horizontal assemblies, disconnect terminal blocks should be mounted with
fixed foot on top (power side) so that the disconnect knife does not partially close through gravity. Furthermore,
as specified per IEC 60947-7-1, disconnect terminal blocks are intended to be used for temporary disconnection
at zero potential and at no load.
The connecting capacity data for one Rigid: Solid/Stranded, or one Flexible conductor (when applicable) is a mandatory information required by IEC, UL and CSA standards (Copper conductors).
All other data are provided as supplementary information only. For more details, please consult our CB, UL or CSA certificates and technical datasheet available on http://www.TE.com
