Mounts on plate or DIN rail, with screw-clamp terminals torqued to 1.3 N·m using a No. 2 Philips or 6 mm flat screwdriver. The 45 mm width and 58 mm height fit standard enclosure cutouts alongside other TeSys K auxiliaries. The AC-1 rating governs resistive loads only; for motor (AC-3) or inductive duty, a different TeSys K variant with a higher AC-3 rating is needed. Breaking capacity reaches 110 A at 440 V, 80 A at 500 V, and 70 A at 660–690 V — sufficient for clearing overloads on a 20 A resistive circuit without welding the contacts. The B10d value of 1,369,863 cycles (nominal load) per EN/ISO 13849-1 gives a reliability benchmark for safety-related resistive load circuits — useful if the contactor is part of a monitored safety function. The 2000 m operating altitude without derating covers most industrial sites; above that, the rated current must be reduced per IEC 60947.","metaTitle":"Schneider Electric LP4K12004SW3 TeSys K Contactor, 4P, 20A A","metaDescription":"TeSys K LP4K12004SW3 contactor, 4 NO poles, 20 A rated operational current at 690 V AC-1, 72 V DC coil.
