The Schneider Electric LC1F1154B7 is a TeSys F 4-pole contactor rated for 200 A in AC-3 duty (motor switching) at up to 440 V, with a 24 V AC control coil at 40–400 Hz. It carries motor power ratings from 18.5 kW (AC-4 at 400 V) up to 80 kW (AC-3 at 660–690 V), making it a fit for medium-to-large induction motor loads on pumps, conveyors, or compressors. The contactor is plate-mounted, not DIN-rail — plan for a backplate or sub-panel in the enclosure layout.
The 200 A figure is the rated operational current (Ie) in AC-3 utilisation category at ≤ 440 V and ≤ 55 °C — that is the motor-switching current, not the resistive-load (AC-1) rating. For AC-1 duty the thermal current (Ith) is higher, but the AC-3 value governs motor contactor sizing. The 55 kW at 400 V AC-3 is the typical three-phase motor it can switch under IEC 60947-4-1. The 4 NO power poles mean all four main contacts close on coil energisation; there are no normally-closed power poles on this variant. The control circuit is 24 V AC, 40–400 Hz, with a hold-in consumption of 8.9–10.9 VA. The coil holds between 0.85 and 1.1 Uc at 55 °C and drops out between 0.2 and 0.55 Uc — important for brownout ride-through planning. Operating time is 35 ms closing, 130 ms opening at rated control voltage. Standards compliance includes IEC 60947-4-1, IEC 60947-1, EN 60947-4-1, EN 60947-1, and JIS C8201-4-1. The rated insulation voltage (Ui) is 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 group C. Overvoltage category III. The contactor carries TH protective treatment for tropical environments.
Mounts on a plate (not DIN rail). Dimensions: 162 mm height, 163.3 mm width, 171 mm depth. Power circuit accepts bar connections (up to 20 x 3 mm busbar), ring-terminal lugs (1 x 95 mm²), or bolted connection; torque to 10 N·m. Control circuit uses screw-clamp terminals accepting 1–4 mm² flexible or solid, torque to 1.2 N·m. The IP2X front face requires shrouds per IEC 60529.
