It uses AC-3 utilisation category, which means it's rated for switching squirrel-cage motors during starting and stopping — the standard duty for contactors in motor starting circuits. Mechanical interlocking is built in, so the star and delta contactors cannot close simultaneously — a requirement for any star delta configuration to prevent a phase-to-phase short. The unit carries approvals under CSA C22.2 No 14, EN 60947-5-1, EN 60947-4-1, IEC 60947-4-1, IEC 60947-5-1, and UL 508, covering both control circuit and power circuit standards.
The LC3D115Q7A64 is listed as obsolete by the manufacturer. If you're holding a last-time-buy window or managing an installed base, this part's mechanical durability of 8 Mcycles gives a sense of the switching life remaining on existing units in the field.
This star delta starter is plate-mounted, not DIN-rail snap-on, so factor in the panel drilling pattern and the 555 mm height, 450 mm width, and 205 mm depth when laying out the enclosure. It arrives pre-wired, which reduces field wiring time but means the internal connections are fixed — verify the coil circuit matches your control voltage before installation. The coil has no built-in suppressor module, so you'll need to add an external RC snubber or free-wheeling diode across the coil if the control circuit drives inductive loads or if PLC outputs are sensitive to back-EMF.
