It is designed for switching resistive loads in control panels and is certified to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. The 20 A AC-1 rating at ≤440 V is the thermal current the contactor can carry continuously in resistive load circuits. For motor loads, the AC-3 rating would be lower — this part is specced for resistive duty, so do not size it for motor starting without checking the manufacturer's derating. The 400-415 V AC coil means it pulls in reliably on a 400 V line, with a hold-in consumption of 4.5 VA and inrush of 30 VA at 20 °C. The 1.3 W heat dissipation matters for enclosure thermal budgeting, especially in a crowded DIN-rail panel. The 4 NO pole configuration with a 400 V coil is common in heating and lighting contactor panels. The associated fuse rating is 25 A gG or 25 A aM for the power circuit. Mechanical robustness is rated for 10-15 Gn shock and 4 Gn vibration with the contactor closed, suitable for industrial environments.","metaTitle":"TeSys K LC1K12004N7 4P Contactor, 20 A AC-1, 400-415 V AC Co","metaDescription":"Obsolete TeSys K contactor LC1K12004N7, 4P 4 NO, 20 A at 440 V AC-1, 400-415 V AC 50/60 Hz coil.
