(1) Protection ensured for the connection cross-sections shown on page 2/33 and for connection via cable.
(2) In the least favourable direction, without change of contact state (coil supplied at Ue).
(3) The closing time “C” is measured from the moment the coil supply is switched on to initial contact of the main poles. The opening time “O” is measured from
the moment the coil supply is switched off to the moment the main poles separate.
