Miniature IEC Magnetic Contactor 120V AC

The Schneider Electric SQUARE D LC2K1201G7 is a miniature IEC magnetic contactor rated for 120V AC coil voltage. It provides three power poles with an inductive full load current of 12 A and a resistive rating of 20 A. One normally closed auxiliary contact is integrated. The unit is designed for DIN rail or plate mounting in industrial control panels.

Coil voltage and current ratings define

The 120V AC coil determines the control circuit voltage required for operation. Switching capacity is limited to 12 A inductive and 20 A resistive loads across the three poles. Reversing capability is supported for motor direction control. The contactor carries no NEMA enclosure rating, so additional protection must be provided by the enclosure builder.

Screw clamp terminals and compact footprint

Screw clamp terminals accept stripped wire for secure connections without specialised tooling. Overall dimensions are 2.28 in height by 3.54 in width, allowing dense packing on standard DIN rails. The transparent housing aids visual inspection of contact status. Mounting flexibility suits both rail and plate installations in space-constrained cabinets.

Questions about this item

Should I pick the 12 A inductive or the 20 A resistive rating for my load?

Use the 12 A figure for inductive loads such as motors or transformers and the 20 A figure for resistive loads such as heaters; both ratings apply to the same three-pole contactor.

What does the 120 V AC coil voltage mean once the contactor is installed in a panel?

The coil will pull in and hold the contacts closed when fed with 120 V AC control power, so the panel’s control circuit must supply that exact voltage.

How does the screw-clamp terminal interface limit the wire size I can use?

Screw-clamp terminals accept solid or stranded conductors that fit the clamp opening; strip length and torque follow the manufacturer’s installation guide.
