It carries a conventional free-air thermal current (Ith) of 20 A at 50 °C and a rated operational current (Ie) of 20 A at ≤440 V, derating to 16 A at <70 °C at 690 V. The coil is 400 V AC at 50/60 Hz, with an inrush of 30 VA and a hold-in draw of 4.5 VA at 20 °C. The 4 NO pole arrangement suits applications where all four circuits need simultaneous make — typically resistive heating banks, lighting groups, or transformer primary switching where no auxiliary break is required. The 400 V AC coil allows direct connection to a 400 V control transformer secondary without an intermediate relay. For motor loads (AC-3), this contactor is not rated; it is a control contactor, not a motor starter. The rated breaking capacity of 110 A at 440 V and 70 A at 660–690 V tells you the contactor can interrupt fault currents up to those levels, but the associated fuse recommendation of 25 A gG or aM sets the practical overcurrent protection limit. The B10d figure of 1,369,863 cycles at nominal load (per EN/ISO 13849-1) gives a reliability benchmark for safety-related circuits. The contactor carries compliance to EN/IEC 60947-4-1, GB/T 14048.4, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. Flame retardance is V1 per UL 94 and meets NF F 16-101/102 Requirement 2. Protective treatment TC per IEC 60068 and DIN 50016 indicates tropicalisation against humidity and condensation.","metaTitle":"Schneider TeSys K LC1K12004V7 Contactor, 4P NO, 20 A AC-1, 4","metaDescription":"Schneider Electric TeSys K LC1K12004V7 contactor. 4P (4 NO), 20 A AC-1 at 690 V, 400 V AC 50/60 Hz coil.
