The LC1K12015P7 is a TeSys K three-pole contactor rated for motor control and resistive loads under utilisation categories AC-3, AC-3e, AC-1, and AC-4. It carries a 12 A rating at 440 V in AC-3/AC-3e duty, with a 230 V AC coil drawing 30 VA inrush and 4.5 VA hold-in at 20 °C, dissipating 1.3 W steady-state.
The 12 A AC-3 rating at 440 V is the headline motor-switching figure — it governs the maximum full-load current of the motor you can control. The AC-4 rating of 72 A (at ≤440 V) is for inching or plugging duty, but electrical durability drops to 0.02 Mcycles under that load, so it's not a continuous jogging contactor. The auxiliary contact is a single 1 NC instantaneous type. Minimum switching capability is 5 mA at 17 V for signalling circuits, so it can drive a PLC input directly without a separate interface relay. The signalling circuit frequency is rated up to 400 Hz.
This contactor carries approvals under EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, JIS C8201-4-1, and several appliance standards (IEC 60335-1 Clause 30.2, IEC 60335-2-40 Annex JJ, UL 60335-2-40 Annex JJ). Flame retardance is V1 per UL 94, and it meets NF F 16-101/102 Requirement 2 for rail-vehicle fire behaviour. Protective treatment is TC per IEC 60068 and DIN 50016, which covers tropical climate resistance.
The LC1K12015P7 is listed as obsolete by Schneider Electric. The solder-pin termination (0.035 mm pin diameter) is specific to PCB-mount or plug-in base applications, so a direct replacement must match that footprint.
Integration notes
The coil has no built-in suppressor module, so an external RC snubber or varistor across the coil terminals is recommended when driven by a PLC output or solid-state relay to limit back-EMF. Operating altitude is 2000 m without derating; shock and vibration ratings (up to 15 Gn shock, 4 Gn vibration closed) suit industrial machinery and mobile equipment.
