The LC1E0901E7 is a 3-pole contactor from the Easy TeSys Control range, rated 9 A in AC-3 utilisation category at up to 440 V. That AC-3 rating tells you it's sized for starting and stopping squirrel-cage motors — the 9 A figure governs the motor full-load current it can switch, not the resistive heating current. For resistive loads (AC-1), the same contactor carries a higher current, but the AC-3 number is the one that decides motor fit. One normally-closed auxiliary contact is built in — enough for a holding circuit or status feedback, but no spare for additional logic without an add-on block.
Mounts on DIN rail or plate. The 45 mm width (3-module footprint) fits standard enclosure rail; depth is 80 mm, height 74 mm. That 80 mm depth matters when you're laying out a shallow panel — it's the dimension that hits the gland plate first.
Standards and environmental limits
Certified to EN/IEC 60947-4-1 (contactor standard) and EN/IEC 60947-5-1 (control circuit devices), plus the Chinese GB/T equivalents. Fire resistance tested to 850 °C per IEC 60695-2-1 — that's the glow-wire test for unattended appliances. No derating needed up to 3000 m altitude. Protective treatment TH (pollution degree 3) per IEC 60068-2-30 means it handles humid, corrosive environments typical of industrial panels — think cement plants or textile mills, not clean rooms.
