The Schneider Electric LC1E0910B6 is a 3-pole contactor from the Easy TeSys Control range, rated for 9 A in AC-3 and AC-3e utilisation categories at up to 440 V, with a 24 V AC 60 Hz coil and one normally open auxiliary contact. It's built for motor control and resistive load switching in control panels, mounting to either a plate or a DIN rail.
The 9 A AC-3 rating is the motor-switching current at 440 V — the figure that decides whether this contactor handles your motor load. AC-3 covers starting and stopping of squirrel-cage motors, where the contacts close on inrush and break the running current. The same contactor also carries an AC-1 rating for resistive loads, so it can switch heaters or lighting banks at a higher current (the exact AC-1 value is not listed here, but the utilisation category is confirmed). The 24 V AC coil at 60 Hz is a fixed-frequency coil — if your panel runs 50 Hz, the coil impedance changes and the pickup/dropout voltages shift. The part is specified for 60 Hz only, so verify coil compatibility before dropping it into a 50 Hz circuit. The non-overlap time of 1.5 ms on both energisation and de-energisation, guaranteed between NC and NO contacts, means the contactor breaks before make — critical for interlocking circuits where you cannot allow momentary shorting across power legs. Mounting is straightforward: 45 mm width on a DIN rail or plate, with an operating altitude of 3000 m without derating. The IP2X finger protection means it's safe for open-panel mounting where accidental contact is possible, but not for washdown environments.
Lifecycle Reality — This Part Is Obsolete
The LC1E0910B6 is marked obsolete by Schneider Electric. There is no official successor order code listed in the available records, so a direct drop-in replacement from the same brand is not confirmed.
The contactor carries compliance with EN/IEC 60947-1, EN/IEC 60947-4-1, EN/IEC 60947-5-1, and the corresponding GB/T standards for the Chinese market. It also meets EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for appliance applications. Fire resistance is tested to 850 °C per IEC 60695-2-1. Protective treatment is TH (pollution degree 3) per IEC 60068-2-30, suitable for humid environments.
