LUCA18BL TeSys U Control Unit, 4.5-18A, 24VDC
The LUCA18BL TeSys U Control Unit, identified by Manufacturer Part Number (MPN) LUCA18BL, is a critical component for sophisticated motor control and protection. This standard control unit from the TeSys U range is specifically designed to handle the protection and control functions of a motor starter, making it ideal for applications in Motor Control Centers, such as those found in wash tunnels, including blower overload protection.
This versatile control unit features a wide thermal protection adjustment range of 4.5 to 18 Amperes and operates with a 24 VDC control circuit voltage. It is equipped with Class 10 thermal overload protection (conforming to IEC 60947-6-2 and UL 508), ensuring rapid tripping for sensitive motor applications. Key protection features include overload and short-circuit protection, earth fault protection, and protection against phase failure and phase imbalance. It also offers a manual reset function for convenience after a trip event.
The LUCA18BL is compatible with LUFN.., LUFC00, ASILUFC51, and ASILUFC5 products and supports AC-41, AC-43, and AC-44 utilization categories. It is capable of controlling motors up to 15 kW at 690V AC, 9 kW at 500V AC, and 7.5 kW at 400-440V AC. The unit employs a self-cooling method for the 3-phase motor load type.
Designed for robust performance, the control unit has a rated insulation voltage of 690V (IEC 60947-1) and 600V (UL 508, CSA C22.2 No 14), with a rated impulse withstand voltage of 6 kV. It features a plug-in mounting mode on the front side and has IP20 protection for the front panel and wired terminals (IP40 for the front panel outside the connection zone). It operates reliably in ambient temperatures from -25°C to 70°C (-13°F to 158°F).
The unit supports advanced functionality through its Modbus connection, allowing for data configuration and transmission, enabling logging and monitoring of functions. It has low typical current consumption and fast operating times (35ms opening, 70ms closing).
The LUCA18BL holds numerous international certifications including UL, CSA, CCC, ABS, BV, DNV, GL, GOST, ATEX, ASEFA, and LROS, ensuring its suitability for a wide range of global applications. It is also a "Green Premium product," indicating a commitment to environmental sustainability.
