Product Description
Benefits & Applications
The Schneider Electric LC1K1210T7 is a compact 12A miniature IEC contactor from the TeSys K series, engineered for reliable motor and load switching in tight commercial and industrial panel spaces. Built with Schneider’s high-endurance TeSys design, this 4kW–5.5kW class contactor provides excellent electrical durability and fast, secure DIN-rail mounting. Its small footprint makes it ideal for OEM equipment, HVAC systems, and automation cabinets where panel depth and width are limited.
The LC1K1210T7 features a 1NO auxiliary contact and a robust 208–240V AC coil. It offers quick installation, quiet operation, and dependable switching for a wide variety of three-phase motor loads and lighting circuits. Because of its compact design, it is frequently used to replace older, bulkier IEC contactors during upgrades or panel redesigns.
Typical Applications
- Small three-phase motors up to 5.5 kW
- HVAC systems, fan coils, and air-handling units
- Commercial and industrial automation equipment
- Compact OEM machinery and process equipment
- Lighting and resistive loads in building control systems
Technical Advantages
- Miniature IEC design for space-critical control panels
- 12A AC-3 rating for reliable motor switching
- Integrated 1NO auxiliary contact (1210 configuration)
- 208–240V AC coil for common HVAC and control voltage applications
- High mechanical endurance for frequent switching
- Easy DIN-rail snap mounting with secure terminal connections
- Compatible with Schneider TeSys K overload relays
Compatibility Notes
The LC1K1210T7 belongs to Schneider Electric’s TeSys K miniature contactor family and is commonly used as a direct replacement for older LC1K12 models with the same coil voltage. It integrates seamlessly with:
- Schneider TeSys K thermal overload relays
- Schneider motor starter accessories and auxiliary contacts
- IEC control panels using compact starter assemblies
If your system requires a 12A, 208–240V AC miniature contactor with a 1NO auxiliary, the LC1K1210T7 is the correct Schneider OEM specification.
Frequently Asked Questions
Q: What does “1210” mean in LC1K1210T7?
“1210” indicates the contactor’s auxiliary configuration:
1 Normally Open (1NO) and 0 Normally Closed (0NC) contacts.
Q: What coil voltage does LC1K1210T7 use?
This model uses a 208–240V AC coil, commonly used in HVAC and industrial control systems.
Q: How is this different from LC1D contactors?
LC1K contactors are miniature and designed for compact panels, while LC1D contactors are full-size IEC contactors for higher-power industrial loads.
Q: Can the LC1K1210T7 mount on DIN rail?
Yes. It snaps directly onto standard 35mm DIN rail and can also be panel-mounted.
Q: What overload relay is compatible with this model?
Schneider TeSys K thermal overload relays designed for miniature starters are typically paired with the LC1K1210T7. Always match the relay's FLA range to the motor rating.
