About Low-voltage Power Distribution Products

Why can not a auxiliary contact unit be installed in S-T100DL or less?
Category : 


This is because the delay time becomes shorter since the rebound force ofa spring against the suction force of a magnetic contactor increases if thecontact "a" is added to a auxiliary contact, although structually it ispossible to install a auxiliary contact unit. It is supposed to meet the delaytime of 1 to 4 seconds, but the delay time can not be guaranteed due tothe addition of a auxiliary contact.
