The utilisation categories AC-1, AC-3, and AC-4 are listed, meaning it handles resistive, standard motor starting, and inching/plugging duty respectively — the AC-4 rating is the one to check for frequent reversing or jogging applications. Motor power capability spans multiple voltage systems: 3 kW at 220–230 V AC, 5.5 kW at 380–415 V AC and 440 V AC, and 4 kW at 480 V AC, 500–600 V AC, and 660–690 V AC, all at 50/60 Hz. This breadth means the same part covers 230 V, 400 V, 480 V, and 690 V line supplies without derating the motor power — useful for a machine builder shipping to multiple regions. ## Fault Current Handling Rated short-time withstand current (Icw) for the power circuit is 115 A for 1 second at 50 °C, tapering to 55 A for 1 minute and 25 A for 15 minutes or more. These values define how long the contactor can carry a fault current before welding or damage — coordination with an upstream fuse or breaker must clear the fault within these time-current curves. The signalling circuit (auxiliary contact) withstands 110 A for 100 ms, 90 A for 500 ms, and 80 A for 1 second. No last-time-buy or surplus-channel dependency applies.","metaTitle":"TeSys K LC7K12107B7 Contactor, 3P, 12 A AC-3, 24 V AC Coil","metaDescription":"Schneider Electric TeSys K LC7K12107B7 contactor, 3P, AC-3 <= 440 V 12 A, 1 NO aux, 24 V AC coil.

A sibling with a different coil voltage (e.g., 24 V DC or 110 V AC) would be the same mechanical platform but with a different coil — verify coil compatibility before substituting. No pin-compatible drop-in with identical ratings exists outside the TeSys K family without checking the mounting footprint and auxiliary contact arrangement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LC7K12107B7","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LC7K12107B7 when reusing this data.
