What the ratings mean for fit
The LC1F330ED is a 3-pole TeSys F contactor with a 48 VDC coil, sized for motor loads up to 160 kW at 400 V AC (AC-3 duty). That AC-3 rating is the one that governs motor switching — it's rated for making and breaking locked-rotor currents typical of squirrel-cage motors. The same contactor also carries an AC-1 resistive load rating and an AC-4 rating for inching/jogging duty, so it covers the full utilisation category range for a direct-on-line starter. Rated breaking capacity is 2640 A per IEC 60947-4-1, which means it can interrupt a fault up to that level without welding the contacts — important for coordination with upstream protection. The associated fuse recommendation is 400 A aM or 500 A gG (≤ 440 V), so plan the branch circuit protection accordingly.
Lifecycle and sourcing reality
There is no official successor order code listed for the LC1F330ED. If you need a drop-in replacement with the same footprint and 48 VDC coil, a parametric cross-reference within the TeSys F range is possible — but that requires a spec-by-spec comparison of the mounting plate, power terminations (lug/bar), and control circuit voltage limits. The LC1F330ED uses a plate mount, not DIN rail, so any replacement must share the same bolt pattern.
Integration notes
Mounts on a plate (not DIN rail) — the power circuit uses bolted lugs (up to 240 mm² ring terminals) or a 30 x 5 mm bar connection. Control circuit wiring is screw-clamp terminals accepting 1–4 mm² flexible or solid. The front face carries IP20 protection with shrouds fitted, so it's safe for open-panel installation as long as the shrouds are in place. Coil hold-in power is 5 W at 20 °C; inrush is 750 W. The DC control circuit operates between 0.85 and 1.1 Uc (about 40.8 to 52.8 VDC) and drops out between 0.15 and 0.2 Uc (7.2 to 9.6 VDC). That wide dropout margin means it's tolerant of voltage sags on the control supply — useful on lines with shared DC buses.
