The Schneider Electric LC1E0910N5WB is a 3-pole (3NO) contactor from the Easy TeSys Control range, rated for 9 A in AC-3 and AC-3e duty at up to 440 V. The coil is 415 V AC, 50 Hz, and it carries one normally-open auxiliary contact. This part is listed as obsolete.
The 9 A AC-3 rating governs motor switching — it handles a 3-phase induction motor load up to that current, not a resistive heater. The AC-3e category adds a higher electrical endurance rating for motor starts. If your BOM calls for a 9 A motor-contactor at 415 V, this is the electrical fit. The 415 V AC coil is a fixed-voltage, 50 Hz-only coil; do not apply it on a 60 Hz supply or with a different coil voltage. Mounting is DIN-rail or plate, with a 45 mm width footprint. The 850 °C glow-wire test per IEC 60695-2-1 means the plastic body is rated for high-temperature fault conditions — relevant for appliance and HVAC applications per EN/IEC 60335 references.
