The Schneider Electric TeSys K LC1K09004M7TQ is a 4-pole contactor with 4 normally-open power poles, a 220-230 V AC coil, and a rated operational current of 20 A in utilisation category AC-1 at 440 V. AC-1 is the utilisation category for resistive or slightly inductive loads — heaters, lighting banks, or furnace elements — where the switching current and the breaking current are essentially the same because there's no significant motor inrush or back-EMF. The coil is AC-operated, no built-in bidirectional peak-limiting diode suppressor, so if you're adding a suppression module externally (recommended for PLC-driven coils or long control-wire runs), match it to the 220-230 V AC coil voltage and expect a standard RC snubber or MOV.

Frequently asked questions
What is the closest alternative to this contactor within the TeSys K family?
The closest pin-compatible sibling is the LC1K09004M7T (same 4-pole, 20 A AC-1, but with a 220 V AC coil instead of 220-230 V). The LC1K09004M7TQ has a wider coil tolerance band (220-230 V), which can help if your control transformer output sags under load. Both share the same 45 mm footprint, same pole configuration, and same auxiliary add-ons.
What is the depth of this contactor?
The depth is 57 mm measured from the DIN-rail mounting foot to the front face of the contactor body.
What compliance documentation is available for this part?
The part carries flame retardance certifications: Class C2 per NF F 16-101 and NF F 16-102 (railway fire behaviour), and V1 per UL 94. Additional compliance (RoHS, REACH, UL listing, IEC 60947) is standard for the TeSys K range but not individually confirmed in this listing.
