The Schneider Electric TeSys F LC1F1400U7 is a 3-pole contactor rated for 1400 A in AC-1 utilisation category, meaning it's built for switching resistive loads like heaters or large lighting banks where the current stays steady through the make and break. The 240 VAC 40-400 Hz coil pulls 2200 VA inrush and holds at 36 VA. It's a plate-mount unit — 438 mm wide, 332 mm tall, 238.6 mm deep — so plan for a substantial footprint in the panel. The power circuit uses bar connections with a 100 x 5 mm busbar cross-section, and tightening torque is 58 N.m on the power side, 1.2 N.m on the control circuit.
