AC-3 is the standard utilisation category for squirrel-cage motors: starting, switching off during running, and plugging/reversing — so the 9 A rating governs the motor current it can handle under those conditions, not a resistive load. It comes in a polycarbonate enclosure rated IP55 (dust- and hose-down protection) and IK07 (impact resistance up to 2 J).
Lifecycle reality — obsolete, but we hold stock
The LG7K09M7 is officially obsolete per Schneider's lifecycle status. That means the factory no longer manufactures it, and there is no scheduled last-time-buy window — what is on the shelf is the final supply. We carry inventory of this exact part and can quote it against an RFQ.
Dimensions, protection, and mounting
The enclosure measures 177 mm deep, 175 mm wide, and 165 mm high — a compact footprint for a motor starter with integral push-buttons and E-stop. Cable entry is provided by four knockouts: two Pg 13 and two Pg 16 on both top and bottom faces, giving flexibility for incoming mains and motor leads. The IK07 impact rating (2 J) means it survives accidental tool drops or bumps without cracking. The device is intended for wall or panel mounting; the circuit-breaker (ordered separately) and contactor are housed inside, so the installer needs only to run the motor and control wiring.
The LG7K09M7 is designed to meet IEC 60204-1 (safety of machinery — electrical equipment) and IEC 60947-4-1 (low-voltage switchgear — contactors and motor-starters). The IP55 and IK07 ratings are verified per IEC 60529 and IEC 60529 respectively. No UL or CSA listing is stated in the available data, so for North American installations verify local code acceptance before specifying.
