The 110 V DC low-consumption coil draws 1.8 W hold-in power. Built to EN/IEC 60947-4-1 and UL 60947-4-1, the contactor carries global approvals for panel builds destined for North America, Europe, or China (GB/T 14048.4). The 1 NO auxiliary contact is rated for signalling circuits down to 5 mA and 17 V, so it can switch PLC inputs directly without a separate interface relay. Depth is 57 mm, height 58 mm. Screw clamp terminals accept 1.5 to 4 mm² solid or stranded, tightening torque 0.8 to 1.3 N·m. The V1 flame-retardance rating per UL 94 means it passes the vertical burn test — important for UL 508A panel certification. ## Electrical durability and safety data Electrical durability is 1.3 million cycles at 9 A AC-3, and 30 million mechanical cycles — the mechanical life far exceeds the electrical, so the contactor will likely be replaced due to contact wear rather than mechanism failure. The B10d value of 1,369,863 cycles (nominal load) per EN/ISO 13849-1 supports use in safety-related control circuits up to PL c or d, depending on the architecture. Coil de-energisation time is 10 to 20 ms, NO opening; energisation takes 30 to 40 ms. That asymmetry matters when sequencing contactors in a reversing starter — the break-before-make gap is about 10 ms minimum.","metaTitle":"Schneider Electric LP4K0910FW3 TeSys K Contactor, 3P, 9A AC-","metaDescription":"LP4K0910FW3 TeSys K contactor, 3 poles, 9 A AC-3/AC-3e at 440 V, 1 NO auxiliary contact, 110 V DC low-consumption coil.
