Schneider Electric LUCMT1BL Multifunction Control Unit

Schneider Electric's TeSys U LUCMT1BL Multifunction Control Unit is a 24 VDC–controlled protection and monitoring module designed for three‑phase motors mounted on a LUTM••BL control base within TeSys U installations. It requires a 24 V DC control circuit supply and provides a single 24 V control input with a coil current rating of about 0.35–1.05 A. The unit mounts on the LUTM••BL base and integrates with TeSys U components such as LUTM overload controllers and LU•B•/LU•S• starters, delivering protection functions including overcurrent protection, adjustable overload trip class (5–30), ground fault detection, protection against phase imbalance, protection against mechanical blockages during or after starting, and under‑load protection. For diagnostics and remote integration, it offers front RS‑485 communication (RJ‑45) and can be configured locally via the TeSys U interface or remotely with PowerSuite software. The LUCMT1BL is intended specifically for AC motor loads, making it suitable for industrial drive systems such as conveyors, pumps, fans, and compressors where reliable motor protection and real‑time monitoring are required in TeSys U motor‑management architectures.
