Schneider Electric LU2B32BL TeSys U Reversing Power Base – 32 A, 3-Pole, 24 V DC Coil, 50 kA @ 440 V AC

Description du produit

The Schneider Electric LU2B32BL is a standard reversing power base from the TeSys U modular motor starter system, designed for 3-phase motor applications up to 15 kW at 400 V AC. It consists of power contacts, a 24 V DC control coil, a padlockable rotary handle, an integrated reverser module, and 1 NO + 1 NC auxiliary signalling contacts. The base is completed by adding a LUC control unit to form a full reversing starter controller with overload and short-circuit protection. Rated 32 A at voltages up to 440 V AC (21 A at 690 V), it delivers a service breaking capacity of 50 kA at 230 V and 440 V AC. The 45 mm wide modular design mounts on DIN rail or by screw fixing, supports up to 3,600 operating cycles per hour, and is certified for worldwide use including marine applications.

Caractéristiques standard

• Reversing Motor Starter Base: Integrates a reverser module (LU2MB0BL) and control coil to form a complete reversing starter when combined with a LUC control unit, enabling forward/reverse operation of 3-phase motors.
• 32 A / 50 kA Rating: Rated operational current of 32 A at ≤440 V AC and service breaking capacity of 50 kA at 230 V and 440 V AC, suitable for motors up to 15 kW at 400 V.
• 24 V DC Control Coil: Low-voltage DC coil with 120 mA typical consumption, compatible with PLC outputs and electronic control systems.
• Integrated 1 NO + 1 NC Auxiliary Contacts: Linked and mirror-type auxiliary contacts per IEC 60947-4-1 provide status feedback and safety-related signalling.
• Modular Plug-and-Play Architecture: Power base, control unit, and add-on modules snap together without tools, enabling quick maintenance and configuration changes.
• Compact 45 mm Width: Space-saving design measuring 45 mm × 224 mm × 126 mm and weighing 1.27 kg, with DIN rail or screw mounting options.
• Certifications internationales : Certified to EN/IEC 60947-6-2, UL 60947-4-1, CSA C22.2 No 14; carries CCC, EAC, ATEX, and multiple marine approvals (ABS, BV, DNV, GL, LROS); Green Premium compliant.
