It mounts on the front of the device and connects via lugs-ring terminals, so it's a straightforward way to pick up feedback signals or interlock logic without extra wiring compartments. The conventional free-air thermal current (Ith) is 10 A at 50 °C, which means each contact path can carry 10 A continuously in a typical panel environment. That's the limit for the block itself, not the contactor it's paired with — the contactor's own rating governs the main power path. The rated insulation voltage (Ui) is 690 V per IEC 60947-5-1, and 600 V per UL and CSA equivalents, so it's comfortable on 400 V or 480 V line-to-line systems with standard margins. Rated operational voltage (Ue) is 690 V AC at 25–400 Hz, covering 50/60 Hz mains and higher-frequency control circuits. The making capacity is rated at 110 A into a 10 MΩ load, which is the inrush the contacts can handle when closing onto a cold load — relevant if the auxiliary contacts switch a solenoid or small relay coil directly. IP20 protection means it's safe from finger contact but not washdown; it belongs inside an enclosure, not on the line side of a panel door. The block measures 38 mm wide by 30 mm high by 35 mm deep, so it adds about 35 mm of depth to the front of the contactor. That's a compact footprint — it won't crowd neighboring devices on a DIN rail if the contactor itself is already spaced for airflow. Operating temperature range is -25 to 50 °C, storage from -50 to 80 °C, and it's rated for altitudes up to 2000 m without derating. The protective treatment is TC conforming to IEC 60068, meaning it's tested for tropical climate conditions — condensation and humidity won't be a surprise failure mode.","metaTitle":"Schneider LA1KN316 TeSys K Auxiliary Contact Block, 3NO+1NC,","metaDescription":"LA1KN316 auxiliary contact block from Schneider TeSys K series. 3NO+1NC contacts, front-mount, lug-ring terminals.
