Overview
The LC3D115F7A64 is a Schneider TeSys Deca star delta starter, order code LC3D115F7A64, rated 115 A across 3 poles with a 3x3 NO power circuit configuration and a 110 V AC coil. This pre-wired unit carries an IP2X front face rating per IEC 60529 and is designed for AC-3 motor switching duty, making it a direct-fit component for a star-delta starting scheme on a 115 A motor branch.
A star delta starter uses three contactors — main, star, and delta — to reduce inrush current during motor start. The LC3D115F7A64 integrates all three contactors in a single pre-wired package, simplifying panel wiring and reducing the component count compared to building the same circuit from individual contactors. The 110 V AC coil voltage is a common control voltage in industrial installations; the pre-wired design includes screw clamp terminals for the power and control connections, and the unit is rated IP2X on the front face for basic finger protection inside an enclosure.
Applications
Star delta starters of this class are used on three-phase induction motors where reduced starting current is required — typically pumps, fans, compressors, conveyors, and other constant-torque or variable-torque loads in industrial and commercial facilities. The pre-wired TeSys Deca format is common in OEM machinery, water treatment skids, and HVAC plant where panel space is at a premium and a consistent, tested assembly is preferred over field-built contactor clusters.
