TeSys LU2B12BL U Reversing Power Base, 12A, 24VDC Control
The LU2B12BL Reversing Power Base is a critical component within the Schneider Electric TeSys U series of self-protected motor starters. This power base is designed to be paired with a contactor to create a complete motor starter unit, offering comprehensive overcurrent protection for both three-phase and single-phase motors. It is commonly utilized in demanding industrial environments, such as the Vacuum Panel in the maintenance room of a car wash tunnel.
This power base is a 3-pole reversing unit with a 12 A nominal current rating (at <= 440V, 12A at 500V, 9A at 690V). It operates with a 24 V DC control circuit voltage via screw clamp terminals. For monitoring and control, it includes 1 NO + 1 NC auxiliary contacts. The device is highly robust, featuring a substantial rated service breaking capacity of 50 kA at 230V and 440V, and 10 kA at 500V.
The LU2B12BL is designed for flexible installation, being both panel and DIN rail mountable. It can operate within a wide supply voltage range of 230-690 VAC at frequencies of 40-60 Hz. The operating temperature range is -13°F to 158°F (-25°C to 70°C) (with specific control unit LUC* types). It also boasts high mechanical durability (15 million cycles) and resistance to shocks and vibrations. The product is UL Listed and CSA Certified, ensuring compliance with safety and performance standards. Its dimensions are approximately 1.77" W x 8.82" H x 4.96" D, with a weight of 2.80 lbs.
