The Schneider Electric TeSys F LC3F330P7 is a pre-wired star delta starter designed for motor control applications. This translates to motor power capability of 160 kW at 220/230 V AC, 280 kW at 380/400 V or 415 V AC, and 315 kW at 440 V AC, all at 50/60 Hz. The control circuit is 230 V AC at 50/60 Hz, with an inrush power of 650 VA at cos φ 0.9. The unit is a 3 x 3P pole configuration (three power poles, each with 3 NO contacts) and includes a built-in auxiliary contact set: 1 NC + 1 NO for the KM1 star contactor, 2 NC + 1 NO for the KM2 line contactor, and 1 NC + 2 NO for the KM3 delta contactor. It does not include a start-delta mechanical interlock, relying instead on electrical interlocking via the contactor sequencing.
The 330 A AC-3 rating is the headline figure for motor switching. AC-3 duty covers starting and plugging of squirrel-cage motors — the current during start-up is typically 6-8x the motor FLA, and this contactor set is designed to make and break those currents reliably. The associated fuse recommendation is 500 A gG or 400 A aM at ≤ 440 V, which provides short-circuit protection without nuisance blowing during motor start. Rated breaking capacity is 2640 A, and rated making capacity is 3300 A, both conforming to IEC 60947-4-1. The rated insulation voltage is 1000 V (IEC 60947-4-1) or 1500 V (VDE 0110 group C), giving headroom for 690 V systems. The operating time is 40-65 ms closing and 100-170 ms opening. These numbers matter for high-duty-cycle applications like conveyor systems or pump sequencing where contactor wear is a design constraint. The control circuit voltage limits are 0.85-1.1 Uc for operation and 0.35-0.55 Uc for drop-out at 40-400 Hz. This means the coil will hold in reliably at 195.5-253 V AC and will drop out cleanly between 80.5-126.5 V AC, preventing chatter on brownout conditions.
Mounting is plate-mount only — no DIN rail option on this frame size. The dimensions are 276 mm deep, 725 mm wide, and 110 mm high. The power circuit connections use bolted connections with M10 bolts, accepting busbars up to 30 x 5 mm or ring terminals up to 240 mm². Control circuit connections are screw clamp terminals accepting 1-4 mm² flexible or solid wire. The unit is pre-wired, reducing field wiring time for the star-delta configuration. Mechanical robustness is specified: 2 Gn vibration (5-300 Hz) with contactor open, 5 Gn with contactor closed; 6 Gn shock (11 ms) open, 15 Gn closed.
Standards compliance includes IEC 60947-4-1, EN 60947-4-1, JIS C8201-4-1, IEC 60947-1, and EN 60947-1. This covers the main international and Japanese standards for contactors and motor starters, which is relevant for export equipment or multi-site approvals.
