The LC1K Series AC Contactor is a high-performance electromagnetic switching device engineered for reliable control of motors, lighting circuits, and industrial loads. Designed for frequent switching applications, this contactor delivers exceptional durability with up to 10 million mechanical operations. It can be seamlessly integrated with thermal overload relays to provide comprehensive motor protection in demanding industrial environments.
The LC1K-09 AC Contactor represents a robust solution for industrial switching and control applications. Built to IEC/EN 60947-4-1 standards, this contactor combines reliability, performance, and versatility in a compact package.
Featuring electromagnetic operation, the LC1K Series ensures rapid response times and consistent performance across a wide range of applications. The contactor is rated for AC-1 and AC-3 utilization categories, making it suitable for both resistive loads and motor control applications.
With its 3-pole main contact configuration and integrated auxiliary contact, the LC1K-09 provides both power switching and control circuit feedback capabilities. The contactor's coil operates reliably across 85-110% of rated voltage for pick-up and maintains engagement down to 20-75% for drop-out, ensuring stable operation even under voltage fluctuations.
The compact 45mm width design allows for high-density panel installations, while the flexible mounting options (DIN rail or screw mounting) provide installation versatility. The contactor is designed to work seamlessly with thermal overload relays, creating a complete motor protection solution.
Electrical Performance: The LC1K-09 is rated for 9A continuous current under AC-3 duty (motor control), with a power rating of 4 kW at 400V. For resistive loads (AC-1), the contactor can handle up to 20A. The device operates across a voltage range up to 690V AC at 50/60 Hz frequency.
Contact Configuration: The contactor features 3 main normally-open (NO) power contacts designated as 1L1-2T1, 3L2-4T2, and 5L3-6T3, plus one auxiliary normally-open contact (13-14) for control and signaling purposes.
Control Circuit: The electromagnetic coil (terminals A1-A2) is available in multiple voltage ratings including 24V, 110V, and 230V AC. The coil is designed to pick up reliably between 85-110% of rated voltage and drop out between 20-75% of rated voltage, providing excellent tolerance to supply voltage variations.
Durability & Performance: Engineered for demanding applications, the contactor offers a mechanical life expectancy of at least 10 million operations and an electrical life of at least 1 million operations under AC-3 conditions. It supports switching frequencies up to 3600 operations per hour.
Environmental Specifications: Operating temperature range: -5°C to +40°C. Storage temperature range: -25°C to +70°C. Vertical mounting position is preferred for optimal performance.
Standards Compliance: Fully compliant with IEC/EN 60947-4-1 standards. CE marked and RoHS compliant for environmental safety.
