The LC1F225FE7: The 315 A AC-3 rating is the motor-switching current at 55 °C — that's the figure you size the contactor against, not the thermal (AC-1) current. At 380-400 V it delivers 110 kW; at 500 V it delivers 129 kW. The coil holds at 115 V AC, 40-400 Hz, with a drop-out range of 0.2-0.55 Uc. Built to IEC 60947-4-1 and EN 60947-4-1, this contactor is rated for motor control and resistive loads.
This part is EOL hot — the manufacturer has ended production.
Plate-mounted, not DIN-rail. Dimensions are 197 mm high, 168.5 mm wide, 181 mm deep. Power connections accept bar (32 x 4 mm busbar), lugs (185 mm²), or bolted connection. Control circuit uses screw clamp terminals for 1-4 mm² flexible or solid wire. Tightening torque: 35 N.m on power, 1.2 N.m on control.
