Nettet9. aug. 2006 · The holding circuit interlock is a normally open auxiliary contact on magnetic starters or contactors. Used in three wire control schemes with momentary inputs. It closes when the coil is energized to form a holding circuit for the starter or contactor after the ``Start`` button or input has been released. Published for: Schneider … NettetDC Circuits Arc is an electric spark that occurs between the contacts when the relay closes the electric circuit. As the voltage and current amplitude increase, the arc rises. When the switch is closed slowly, it takes longer time for an arc to form. This can cause the contacts to wear out quickly.
