The Schneider TeSys K LC2K16105FC7 is a reversing contactor — three poles, normally open, with a 127 V AC coil. It's rated for AC-3 duty up to 16 A at 440 V, which means it's sized for reversing a three-phase motor of about 7.5 kW (10 hp) on a 400 V line. The AC-4 rating covers plugging and inching, so it'll handle the occasional reversal under load without welding the contacts. That's a time-saver on a panel build — just mount it, land the line and load, and you're done with the reversing circuit.
This contactor lives inside an IP20 enclosure — no washdown, no outdoor exposure. It's meant for a dry control cabinet, DIN-rail mounted, with the gland plate keeping dust out. Storage range goes from -50 to 80 °C, which covers shipping and spares on a shelf. Altitude derating kicks in above 2000 m — if you're installing at elevation (say, a mine or high-altitude plant), you'll need to reduce the current or add forced cooling.
Tough enough for the route
Out here in the grease, vibration kills contacts. This one's tested to 4 Gn closed, 2 Gn open across 5–300 Hz, and shock-rated at 10–15 Gn depending on axis. That's enough for a conveyor drive or a pump skid — it won't chatter open on a bumpy line. Flame retardance meets UL 94 V1 and NF F 16-101/102, so it's acceptable for rail and transit applications where the fire code is strict.
