The Schneider Electric LG7D12N716 is an enclosed direct-on-line (DOL) starter from the TeSys LG range, combining a contactor and a circuit-breaker in one IP55-rated polycarbonate enclosure with an IK07 impact rating. It's built for safety applications — the front panel carries a white push-button start, a black push-button stop, and a red mushroom-head emergency stop, so an operator can control and cut power right at the machine without reaching for a separate panel. The thermal overload protection is adjustable from 9 to 14 A, and the control coil is 415 V AC, 50/60 Hz.
Motor ratings and what AC-3 means for your load
Rated in utilisation category AC-3 (squirrel-cage motor starting, breaking during running), this starter handles 3 kW at 220/230 V AC and 5.5 kW at 400/415 V AC or 440 V AC, all at 50/60 Hz. AC-3 is the standard duty for most induction motors on pumps, fans, and conveyors — it means the contactor is rated to make and break the motor's locked-rotor current, not just its running current. If your motor is within those power bands and your supply matches the 415 V AC coil, the fit is straightforward.
Standards compliance
Designed to IEC 60947-4-1 (contactors and motor-starters) and IEC 60204-1 (safety of machinery — electrical equipment), so it meets the core international standards for industrial motor control and machine safety circuits.
