Overview
The LC1F330F7 is a Schneider TeSys F direct-on-line contactor rated for 400 A switching current across AC-1, AC-3, and AC-4 utilization categories, with a 110 V AC coil accepting 40-400 Hz control supply. It carries marine and industrial certifications including BV, DNV, CSA, ABS, UL, CB, RMRoS, LROS, RINA, and UKCA, and is rated for 3000 m altitude without derating.
The 400 A switching current and 0.28 mOhm average impedance at 400 A 50 Hz suit it for high-current motor and resistive loads; the 8 W heat dissipation and 10 Mcycles mechanical life support continuous-duty panels. Associated fuse rating of 400 A aM or 500 A gG at ≤ 440 V provides a coordination baseline for short-circuit protection sizing.
Compared to the LC1D150M7 (200 A switching current, 100 hp at 460 VAC), the LC1F330F7 doubles the switching current to 400 A and covers AC-4 duty, making it the choice for higher-current reversing or plugging applications.
