with fixed foot on top (power side) so that the disconnect knife does not partially close through gravity.
5.2 mm 0.205 in spacing
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).
