Schneider Electric TeSys U LUCA05BL Standard Control Unit 1.25-5A Class 10 24V DC 690V

Product Description

The Schneider Electric LUCA05BL is a TeSys U standard control unit designed for motor control and protection applications. It provides an adjustable thermal protection range of 1.25 to 5 A and Class 10 overload protection for three-phase motors. The unit operates with a 24 V DC control circuit and supports rated operational voltages up to 690 V AC. Integrated protection functions include overload, short-circuit, phase failure, phase imbalance, and earth-fault protection. Designed for modular TeSys U motor starters, the LUCA05BL plugs directly into compatible LUB and LU2B power bases, simplifying installation, replacement, and maintenance in industrial motor-control systems.

Standard Features
