The Schneider Electric LC7K09105B7TQ is a 3-pole silent contactor from the TeSys K series, rated 20 A in AC-1 utilisation category and 9 A in AC-3 at 440 V — so it handles resistive loads up to 20 A and motor loads up to 9 A. The 24 V AC coil includes a built-in bidirectional peak limiting diode suppressor, which suppresses back-EMF on de-energisation without an external snubber.
The 3 NO power poles and AC control circuit are straightforward to wire; the built-in coil suppression simplifies panel layout by eliminating the need for a separate flyback diode or RC network.
Flame retardance and compliance
Flame retardance rated Class C2 per NF F 16-101 and NF F 16-102, plus V-1 per UL 94 — relevant for rail and industrial applications requiring fire-smoke-toxicity compliance. The TeSys K series carries the usual Schneider documentation package (declaration of conformity, material data sheets) available on request.
