Schneider Electric Direct On Line (DOL) Starter 3 kW 3 Phase 690V AC IP40 LUCA05FU

Schneider Electric LUCA05FU Direct On Line (DOL) Starter is a compact and reliable control unit specifically engineered for starting and protecting three-phase motors with a power rating of up to 3 kW at 690V AC. The device integrates advanced thermal-magnetic overload and short-circuit protection combined with phase loss and imbalance monitoring to ensure motor safety and operational efficiency in demanding industrial environments.

This DOL starter features adjustable current protection ranging from 1.25 to 5 amperes, providing effective safeguarding of motor windings against overloads. It is designed with a Class 10 thermal release mechanism offering a time-delayed overload response, enhancing protection accuracy. The starter accepts a versatile control supply voltage of 110 to 240V AC or 110 to 220V DC, accommodating varied control panel requirements.

Engineered for hazardous-area installations, the LUCA05FU carries ATEX certification. It also conforms to rigorous international safety and performance standards including CSA C22.2 No. 14 Type E, UL 508 Type E, IEC 60947-6-2, and EN 60947-6-2. The device has an IP20 front and IP40 front-outside protection rating, ensuring robustness for panel mounting in harsh industrial settings.

With dimensions of 66 mm length, 45 mm width, and 60 mm depth, this starter is optimized for installation flexibility. It operates efficiently within ambient temperatures from -25°C up to 70°C, suitable for a wide range of industrial environments, and stores safely down to -40°C. The unit is rated for altitudes up to 2000 meters, making it suitable for diverse geographical applications.

LUCA05FU is compatible with plug-in power bases such as the LUB12 and LUB32, facilitating easy integration within motor control panels. Application areas include machinery requiring reversing contactor to breaker assemblies, hazardous area motor starting, and scenarios necessitating phase-failure protection. Typical switch operation times are approximately 50 ms to close and 35 ms to open on compatible bases.
