Schneider Electric TeSys Deca LC1D09M7 Contactor

Schneider Electric LC1D09M7 is a TeSys Deca 3-pole contactor with three normally open (3 NO) main contacts for controlling motors and industrial electrical loads. It is rated at 9 A in AC-3 duty at up to 440 V AC and uses an M7 220 V AC, 50/60 Hz coil.

Functions and key features

• Integrated 13–14 normally open (NO) and 21–22 normally closed (NC) auxiliary contacts for seal-in, interlocking, status indication, or control logic.
• Power input terminals: 1/L1, 3/L2, 5/L3; load output terminals: 2/T1, 4/T2, 6/T3.
• Control coil terminals: A1–A2.
• Screw clamp terminals with DIN rail or plate mounting.
• The front indicator shows the mechanical status of the contactor; it is not a standard ON/OFF button.

Applications

LC1D09M7 is suitable for control panels, MCCs, direct-on-line (DOL) starters, industrial machinery, pumps, fans, conveyors, compressors, HVAC, and M&E systems. For three-phase motors in AC-3 duty, the published reference motor power is 2.2 kW at 220–230 V AC and 4 kW at 380–440 V AC.

Selection and safety notes

Verify motor voltage, rated current, load type, switching duty, 220 V AC coil voltage, and auxiliary-contact requirements before selection. LC1D09M7 is a switching control device and does not replace overload or short-circuit protective devices. A motor starter must be coordinated with suitable protection according to the load and system requirements.
