Covers 50/60 Hz supplies. ## Coil suppression built in — no external diode needed The coil includes a built-in bidirectional peak-limiting diode suppressor. No external flyback diode or RC snubber needed across the coil terminals. ## Thermal and mechanical fit Heat dissipation is 1.3 W — low enough that you can pack it in a control cabinet without worrying about derating adjacent components. The flame-retardant housing carries a UL 94 V1 rating and meets NF F 16-101/102 requirements, which matters for rail and transit applications.","metaTitle":"Schneider TeSys K LC1K1210FC72 Contactor, 3P, 12 A AC-3, 36","metaDescription":"Active TeSys K contactor, 3 poles, AC-3 rated 12 A at ≤440 V, 1 NO aux contact, 36 V AC coil.

The LC1K1210FC72 uses a 36 V AC coil. If your control voltage is different, the same contactor body with a different coil code is the direct alternative — same pole configuration, same current ratings, same aux contact count."},{"question":"What is the depth of the LC1K1210FC72?","answer":"The depth is 57 mm.

The TeSys K range is typically covered by RoHS, REACH, and UL/CSA certifications, though specific documentation should be verified against the factory certificate for this exact order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LC1K1210FC72","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/LC1K1210FC72 when reusing this data.
