Industrial LUB12-LUCB05BL Motor Starter With Control Unit

The Industrial LUB12-LUCB05BL Motor Starter With Control Unit is a TeSys U modular combination motor starter that pairs a LUB12 power base with the LUCB05BL advanced control unit for intelligent motor starting, protection, and diagnostics on three‑phase motors up to 690 VAC. It provides adjustable control current from 1.25 to 5 A and uses a 24 VDC coil, enabling integrated overload, short‑circuit, phase‑loss, and earth‑fault protection within a compact plug‑in assembly. The unit is rated for 12 A base current with a 3‑pole configuration and is designed for use in motor control centers, conveyors, pumps, compressors, packaging machinery, and other industrial automation systems needing reliable monitoring and diagnostics. Common replacements include Schneider Electric LUCB05BL and Telemecanique LUCB05BL; it is compatible with LUB12, LUB32, LUB38, LUB120, LUB320, LUB380 systems and LU2B reversing contactor breakers. Key protections include Class 10 thermal overload, short circuit, phase loss, phase imbalance, and earth fault protection, making it a direct OEM replacement for integration where advanced communication capabilities and dependable motor protection are required.
