Product Description

The LC1G400KUEN by Schneider Electric is a heavy-duty TeSys D Contactor designed for industrial motor control, delivering reliable 400A switching capacity in high-power applications. This 400A Motor Starter Relay features a 3-pole design with 1 NO+1 NC auxiliary contacts for control circuits, compatible with standard modular accessories like thermal overload relays. It operates across 220-690V AC voltage ranges and withstands ambient temperatures from -25°C to +60°C, meeting IEC/EN standards. Widely used in manufacturing, mining, and energy sectors, its compact design enables space-optimized panel integration. Key strengths include arc-quenching technology for safe operation, 100,000+ mechanical cycles durability, and screw-clamp terminals for secure connections. While optimized for direct motor starting, it requires external protection devices for complete circuit safety. Unlike smart relays, it lacks built-in communication interfaces but pairs seamlessly with Schneider's communication modules for system integration. Maintenance involves periodic contact inspection to ensure optimal performance in harsh environments.
