TeSys LUB32 Self-Protected Starter Power Base (32A, Non-Reversing, 3-Pole)
The LUB32 TeSys U Line Self-Protected Starter Power Base is a robust and essential component for motor control applications, particularly suitable for use in Motor Control Centers within demanding environments like the backroom of a car wash tunnel. This power base is designed to be paired with a contactor (e.g., TeSys U control unit) to form a complete and comprehensive motor starter unit, offering integrated overcurrent protection for motors.
This 3-pole non-reversing power base is engineered to work seamlessly with both three-phase and single-phase motors, providing critical safety and operational reliability. It features screw clamp terminals for secure and straightforward wiring of both power and control circuits, accommodating a wide range of cable sizes. The LUB32 has a high conventional free air thermal current of 32 Amperes, indicating its capacity for continuous operation. It can handle rated operational currents of 32A at <= 440V, 23A at 500V, and 21A at 690V.
A key feature of this power base is its integrated 1 NO (Normally Open) + 1 NC (Normally Closed) auxiliary contact composition, which includes linked and mirror contacts. These auxiliary contacts are vital for signaling and interlocking within complex control schemes. The LUB32 is highly flexible in terms of control voltage, supporting a wide range including 24V AC/DC, 48V AC/DC, and 110-220V DC / 110-240V AC. It operates with a supply voltage range of 120-600 VAC and a frequency of 40-60 Hz. With a high rated service breaking capacity of 50 kA at 230V and 440V (10 kA at 500V, 4 kA at 690V), it provides robust short-circuit protection.
The power base is designed for ease of installation, supporting both panel and DIN rail mounting. It operates reliably across a wide ambient air temperature range of -13°F to 158°F (-25°C to 70°C, depending on the control unit). The LUB32 boasts an impressive mechanical durability of 15 million cycles, ensuring a long operational life. It is extensively certified by major international standards (UL Listed, CSA Certified, IEC, ABS, GL, GOST, ATEX, etc.), underscoring its quality and suitability for global applications. As a Green Premium product, it also emphasizes environmental sustainability.
