The LC1K1610U7 is a 3-pole contactor from the TeSys K series, rated 16 A in AC-3 and AC-3e utilisation categories at ≤440 V. The AC-3e suffix means it also meets the more stringent electrical endurance requirements of the IEC AC-3e standard, which is common in European panel specs. The 230-240 V AC coil is a standard industrial control voltage, and the contactor draws 30 VA inrush and 4.5 VA hold-in power at 20 °C, so a 50 VA control transformer is adequate for a single unit. Electrical durability is rated at 1.3 million cycles at 16 A AC-3 / AC-3e at ≤440 V — that is the expected life under full rated motor load. Mechanical durability is 10 million cycles, which is the no-load life. For a machine that cycles once every 10 seconds, the electrical life translates to roughly 150 days of continuous operation at rated load; the mechanical life is about 1.5 years at the same rate. The B10d safety reliability figure of 1,369,863 cycles under nominal load (per EN/ISO 13849-1) means 10% of a population of these contactors would have reached end of life by that count — useful for safety circuit SIL/PL calculations.
Screw clamp terminals accept 1.5 to 4 mm² solid or 0.75 to 4 mm² flexible wire (with or without ferrules), and the tightening torque range is 0.8 to 1.3 N·m. The IP2X finger protection (per VDE 0106) means it is safe for open-panel mounting where incidental contact is possible, but not for washdown environments. Heat dissipation is 1.3 W at rated coil voltage — negligible for panel thermal calculations, but worth noting if the contactor is packed tightly with other heat sources.
The LC1K1610U7 carries approvals to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. It also meets the glow-wire test requirements of IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ, which is relevant for appliances and HVAC equipment. The enclosure material is rated V1 per UL 94 for flame retardance. Protective treatment is TC per IEC 60068 and DIN 50016, meaning it is tropicalized — suitable for humid or corrosive environments without additional coating.
