The Schneider Electric LC3K06B7 is a TeSys K star delta starter, pre-wired with 3 x 3P (3 NO) power poles, rated for 6 A and a 24 V AC coil. It is designed for motor control under utilisation category AC-3, meaning it handles the high inrush currents of squirrel-cage motors during starting and stopping — the standard duty for contactors in a star-delta transition.
The 6 A rating under AC-3 duty governs the maximum motor current the starter can switch — sized for a small motor, typically up to about 2.2 kW at 400 V three-phase. The 24 V AC coil is a control-circuit voltage common in panel designs, but verify your transformer or PLC output matches AC, not DC. The V-0 flame retardance rating (UL 94) confirms the housing material self-extinguishes within 10 seconds, a standard requirement for panel-mounted components.
Integration notes
The pre-wired design reduces panel wiring time — the star-delta interconnections are factory-terminated. The 3 x 3P pole arrangement (three NO contacts per pole) suits a standard six-contact star-delta circuit. Mounting is on a DIN rail; the IP20 housing fits inside a control cabinet. Ambient storage range of -50 to 80 °C covers most warehouse conditions, but operating temperature limits should be checked against the enclosure's internal rise.
