The LE3D35Q7 is a Schneider Electric TeSys LE enclosed star-delta starter rated for 35 A in AC-3 utilisation category, meaning it is sized for switching three-phase induction motors under starting and running conditions. The 35 A AC-3 rating directly governs the motor current it can handle — at 380/400 V AC this translates to 22 kW motor power. The polycarbonate enclosure carries an IP65 rating, making it suitable for washdown environments or outdoor installation where hose-directed water is a concern.
For a requalification, a panel builder would need to evaluate a current-generation enclosed starter from the TeSys range that matches the 35 A AC-3 rating, 380 V AC coil voltage, and IP65 enclosure — the physical footprint and cable entry layout would also need verification.
The 35 A rated operational current in AC-3 is the figure that determines whether this starter can handle the motor full-load current plus the inrush during start. AC-3 covers starting and switching off of squirrel-cage motors during running — the standard duty for star-delta starters. The motor power table gives the practical match: 22 kW at 380/400 V, 26 kW at 415/440 V. The enclosure dimensions — 348 mm height, 186 mm width, 175.5 mm depth — and the polycarbonate material with IK07 impact resistance mean it fits in a standard industrial panel or wall-mount location where moderate mechanical protection is needed. Cable entries include multiple ISO20, ISO25, ISO32, and ISO40 knockouts top and bottom for routing power and control wiring. The starter is supplied without a thermal overload relay — that must be ordered separately and mounted to the contactor assembly. The device composition also notes that star-delta contactors and a mechanical interlock are part of the assembly, so the unit arrives as a pre-configured star-delta set ready for the overload relay addition.
The LE3D35Q7 is designed to IEC 60947-4-1, the standard for contactors and motor-starters. The IP65 and IK07 protection ratings are verified per IEC 60529.
