The Schneider Electric TeSys LG1K065Q710A37 is an enclosed direct-on-line (DOL) starter that integrates a contactor, switch disconnector, and circuit-breaker in a single polycarbonate enclosure rated IP55 and IK07. It is designed for standard-environment motor starting and safety isolation, with a thermal protection adjustment range of 4…6.3 A and an AC-3 utilization category for three-phase induction motors up to 3 kW at 440 V AC. Cable entries are provided: 4 Pg 13 + 2 Pg 16 at both top and bottom.
Because this is an obsolete part, buyers should verify fit against the original application and consider whether an official replacement or a functionally equivalent enclosed starter from the current TeSys range can be specified. The manufacturer's lifecycle documentation may list a successor order code; if none is available, a parametric cross-reference based on motor power, thermal range, and enclosure rating is the practical path.
The 4…6.3 A thermal protection adjustment range sets the motor full-load current window this starter can protect. For a 3 kW motor at 440 V AC (AC-3 duty), the thermal overload is set within that band. The IK07 impact rating means the enclosure withstands a 2 J impact — adequate for general panel or machine-side mounting.
Deployment context
This enclosed DOL starter is a self-contained unit — no separate contactor, overload relay, or enclosure to assemble. It mounts directly to a machine frame or wall via the polycarbonate enclosure's fixing points. The cable entries (Pg 13 and Pg 16) accept standard industrial cable glands for motor and supply wiring. The integrated push-button controls and emergency stop reduce external panel wiring. The rotary-handle emergency stop provides a lockable, positive-break isolation point that satisfies IEC 60204-1 and IEC 60947-4-1 requirements for safety disconnection.
