Information About LC1G800KUEN

The LC1G800KUEN is part of Schneider Electric’s TeSys Giga range, a series of high-power contactors designed for motor control and power switching in large industrial assemblies. It has a 3P (3 NO) main pole arrangement, an embedded 1 NO + 1 NC auxiliary contact block, and front-access control connections that support faster service and replacement in panel installations. The unit uses a 100–250 V AC/DC low-consumption electronic coil with built-in bidirectional peak limiting, and it includes Local Contact Wear Diagnosis for continuous contact-health indication. It is intended for high-load applications where durability, serviceability, and stable operation at temperatures up to 60 °C are required.

Key Features:

• High AC-3 current rating: Rated for 800 A at up to 440 V AC-3 for heavy-duty motor switching.
• Wide-band electronic coil: Uses a 100–250 V AC/DC coil for flexible control voltage compatibility.
• TeSys Giga platform: Built within Schneider Electric’s high-power TeSys Giga contactor range for large industrial systems.
• Integrated auxiliary contacts: Includes 1 NO + 1 NC auxiliary contacts as a built-in standard feature.
• Contact wear monitoring: Local Contact Wear Diagnosis provides health and alarm indication for contact condition.
• Replaceable switching module: Main contacts can be replaced to help extend service life and simplify maintenance.
• High mechanical endurance: Rated for 5 million mechanical operating cycles in demanding duty.
• Broad application coverage: Supports AC and DC utilization categories including AC-1, AC-3, AC-3e, AC-4, and DC-1/DC-3/DC-5.

The LC1G800KUEN delivers the reliability and precision required for high-power motor control and industrial power switching systems.
