Miniature contactor, transparent housing, DIN-rail mount, 1.77 by 2.28 inches

Schneider Electric

Schneider Electric Square D LC1K1210G7 120V 3P 1NO 12A 20A 1.77x2.28in

SKU CH-RM1X-MB7KX

Miniature IEC magnetic contactor with 1NO auxiliary contact, 120V AC coil, 3 poles, 12A inductive and 20A resistive ratings, screw clamp terminals, DIN rail or plate mounting.

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Compact 1.77 × 2.28 in footprint fits tight panels
  • 120 V AC coil simplifies standard control wiring
  • 12 A inductive and 20 A resistive ratings cover mixed loads
  • 3-pole non-reversing design suits straightforward motor switching

Schneider Electric Square D TeSys K Contactor

This miniature IEC magnetic contactor is designed for industrial electrical control and automation panels. It provides three-pole switching at a 120V AC coil voltage with a single normally open auxiliary contact. The unit mounts on DIN rail or plate and uses screw clamp terminals for secure wiring connections.

Sustained load performance

The contactor carries a full-load inductive current of 12 A and a resistive current of 20 A during continuous operation. Its non-reversing design maintains stable engagement without mechanical reversal wear. The open enclosure style allows unrestricted airflow around the contacts for consistent thermal performance under load.

Replaces larger IEC contactors

This compact TeSys K series unit fits where standard frame contactors cannot, measuring 1.77 in wide by 2.28 in high. The upgrade is worthwhile when panel space is limited but 3-pole switching at 12 A inductive rating is still required. It is not suited for applications needing reversing capability or additional auxiliary contact blocks.

Questions about this item

Does the 120 V AC coil on the LC1K1210G7 run hot or draw much power when energised continuously?

The coil is rated for 120 V AC operation; continuous duty is within the IEC design limits of the TeSys K series contactor.

What wiring and mounting hardware must I already have to install this contactor?

You need screw-clamp terminal wiring and a DIN rail or mounting plate for the 1.77 in by 2.28 in footprint.

Will this 3-pole 12 A inductive contactor coordinate with my existing motor starters and overload relays?

It provides 3 power poles plus 1 NO auxiliary contact, matching standard IEC starter schemes for 12 A inductive loads.
