The Schneider Electric LC1K16016K7 is a TeSys K series 3-pole contactor rated for motor control in AC-3 and AC-3e utilisation categories, switching 16 A at up to 440 V. The 100 V AC coil draws 30 VA inrush and 4.5 VA hold-in power at 20 °C, with an operating range of 0.8 to 1.15 Uc and a drop-out threshold above 0.20 Uc below 50 °C. A built-in 1 NC instantaneous auxiliary contact handles signalling circuits down to 5 mA and 17 V.
Standards and compliance — what crosses a border cleanly
This contactor carries certification to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, GB/T 14048.4, and JIS C8201-4-1, plus IEC 60335-1 and UL 60335-2-40 Annex JJ for appliance applications. The flame-retardant housing meets V1 per UL 94. For a sourcing desk, that means the paperwork is clean for North America, Europe, China, and Japan — no last-minute customs holds on a BOM line that needs to land DDP.
Mounting and integration into a panel
The contactor mounts to a plate or DIN rail, with a footprint of 45 mm wide by 58 mm high by 57 mm deep. Connections are via lug-ring terminals accepting an external diameter of 7 mm, torqued to 0.8...1.3 N·m using a Philips No 2, flat Ø 6 mm, or Pozidriv No 2 driver. The IP2X finger protection per VDE 0106 is adequate for enclosed panel use but not for washdown environments.
Durability and mechanical robustness
Rated for 10 million mechanical cycles and 1.3 million electrical cycles at 16 A AC-3/AC-3e up to 440 V. The contactor withstands shock up to 15 Gn on Y and Z axes when closed, and vibration up to 4 Gn from 5 to 300 Hz when closed. Safety reliability figures are B10d = 1,369,863 cycles under nominal load and B10d = 20,000,000 cycles under mechanical load per EN/ISO 13849-1.
