The Schneider Electric LC1E0901R5 is a 3-pole contactor from the Easy TeSys Control range, rated 9 A in AC-3 duty at ≤440 V — meaning it switches standard three-phase squirrel-cage motors up to roughly 4 kW at 400 V. The 440 V AC 50 Hz coil pulls in at nominal voltage; the 1 NC auxiliary contact is wired for status feedback or safety interlock.
The 9 A AC-3 rating is the motor-switching current, not the resistive (AC-1) rating — AC-3 covers starting and plugging of cage motors, where the contactor sees 5–7× inrush. The utilisation categories are AC-3, AC-3e, and AC-1, so it handles both motor and resistive loads. The non-overlap time of 1.5 ms on energisation and de-energisation between NC and NO contacts is a safety-relevant spec: it guarantees that the NC and NO poles are never simultaneously closed during transition, which matters if the NC is used in a safety chain or as a mechanical interlock.
Protective treatment TH (pollution degree 3) per IEC 60068-2-30 means it withstands humid, polluted environments typical of industrial panels. Standards compliance includes EN/IEC 60947-4-1 (contactor spec) and EN/IEC 60947-5-1 (control circuit devices), plus GB/T equivalents for China-market installs.
