What the ratings mean for fit
The LC1G4004LSEN: The 400 A AC-3 rating covers motor switching at up to that current; for resistive loads the Ith is 550 A per pole (30 W dissipation). Mechanical durability of 8 Mcycles suits high-cycling applications. Rated making capacity is 5090 A at 440 V, breaking capacity 3480 A at 440 V — figures that matter for coordination with upstream protection. The contactor is also listed for safety functions with B10d = 400,000 cycles at nominal load.
Integration and mounting
Mounts on a plate (plate mounting listed). Envelope dimensions: depth 226 mm (8.9 in), width 185 mm (7.3 in), height 225 mm (8.9 in); connection pitch 45 mm (1.8 in).
