The Schneider Electric LC1E1201B5 is a 3-pole contactor from the Easy TeSys Control range, rated for 12 A in AC-3 utilisation category at up to 440 V, with a 24 V AC 50 Hz coil and one normally-closed auxiliary contact. Rated for AC-3, AC-3e, and AC-1 categories, the 12 A AC-3 rating is the one that governs motor switching — this contactor handles a 3-phase motor load up to that current without welding the main poles. The AC-1 rating for resistive loads is higher, but for motor duty the AC-3 figure is the binding spec.
Mounts on both plate and DIN rail (35 mm), with a 45 mm width footprint that fits standard enclosure gland plates. The 80 mm depth leaves clearance for wiring ducts and panel doors.
Operates from -5 °C to 55 °C ambient, with storage from -60 °C to 80 °C. Fire resistance at 850 °C conforms to IEC 60695-2-1, a key requirement for appliance and HVAC applications referenced in EN/IEC 60335-1 and -2-40. The 3000 m operating altitude without derating covers most high-altitude installations without needing to reduce the rated current.
