Product Description
Benefits & Applications
The Schneider Electric LC1K1210Q7 is a compact 12A miniature IEC contactor from the TeSys K series, engineered for dependable switching of three-phase motors and control circuits in space-constrained electrical panels. Its rugged TeSys design, quiet operation, and long electrical endurance make it ideal for HVAC equipment, automation systems, and OEM machinery where compact size and high reliability are essential.
This model features a 1NO auxiliary contact (1210 configuration) and a durable 277V AC coil (Q7), supporting direct use in commercial and industrial control systems that operate on 277V lighting or power circuits.
Typical Applications
- Three-phase motors up to 5.5 kW
- HVAC systems, air handlers, fan coils, and condensers
- Compact OEM and automation control panels
- Lighting and resistive loads in 277V systems
- General industrial control and interlocking circuits
Technical Advantages
- Miniature TeSys K footprint for tight panel layouts
- 12A AC-3 rating for reliable motor switching
- Integrated 1 Normally Open (1NO) auxiliary contact
- 277V AC coil (Q7) for commercial lighting and building systems
- High mechanical and electrical endurance
- Fast DIN-rail snap mounting or panel mounting
- Compatible with Schneider TeSys K thermal overload relays
Compatibility Notes
The LC1K1210Q7 is part of Schneider Electric’s TeSys K miniature contactor line and is commonly used as a direct replacement for prior LC1K12 models that share the same coil voltage. It integrates cleanly with:
- Schneider TeSys K overload relays
- LC1K miniature starter accessories
- Compact IEC motor starter assemblies
If you require a 12A, 277V AC coil, miniature contactor with a 1NO auxiliary contact, the LC1K1210Q7 is the correct Schneider OEM part.
Frequently Asked Questions
Q: What does “1210” mean in LC1K1210Q7?
“1210” defines the auxiliary configuration: 1 Normally Open (1NO), 0 Normally Closed (0NC).
Q: What coil voltage does the LC1K1210Q7 use?
The “Q7” coil code specifies a 277V AC coil, commonly used in commercial building and lighting systems.
Q: How is LC1K different from LC1D contactors?
LC1K contactors are miniature IEC contactors designed for compact panels, while LC1D contactors are full-size industrial IEC contactors for higher-power loads.
Q: Does this contactor mount on DIN rail?
Yes. The LC1K1210Q7 mounts to standard 35mm DIN rail or can be panel mounted.
Q: Which overload relay pairs with the LC1K1210Q7?
Use Schneider TeSys K thermal overload relays, selected to match your motor's full-load current (FLA).
